7 CHAPTER 1 Cisco ATA 191 Analog Telephone Adapter Overview Your Analog Telephone Adapter, page 1 Your Analog Telephone Adapter The ATA 191 analog telephone adapter is a telephony-device-to-ethernet adapter that allows regular analog phones to operate on IP-based telephony networks. The ATA 191 supports two voice ports, each with an independent phone number. The ATA 191 also has an RJ-45 10/100BASE-T data port. Figure 1: Cisco Analog Telephone Adapter 1

8 Session Initiation Protocol Cisco ATA 191 Analog Telephone Adapter Overview Session Initiation Protocol Session Initiation Protocol (SIP) is the Internet Engineering Task Force (IETF) standard for real-time calls and conferencing over Internet Protocol (IP). SIP is an ASCII-based, application-layer control protocol (defined in RFC3261). It is used to establish, maintain, and terminate multimedia sessions or calls between two or more endpoints. Like other Voice over IP (VoIP) protocols, SIP is designed to address the functions of signaling and session management within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management is used to control the attributes of an end-to-end call. Note SIP for the ATA 191 is compliant with RFC2543. SIP Capabilities Session Initiation Protocol (SIP) provides these capabilities: Determines the availability of the target endpoint. If the target endpoint is unavailable, SIP determines whether the called party is already on the phone or didn't answer in the allotted number of rings. SIP then returns a message indicating why the target endpoint was unavailable. Determines the location of the target endpoint. SIP supports address resolution, name mapping, and call redirection. Determines the media capabilities of the target endpoint. Using the Session Description Protocol (SDP), SIP determines the lowest level of common services between endpoints. Conferences are established using only the media capabilities that all endpoints support. Establishes a session between the originating and target endpoint. If the call can be completed, SIP establishes a session between the endpoints. SIP also supports midcall changes, such as adding another endpoint to the conference or changing the media characteristic or codec. Handles the transfer and termination of calls. SIP supports the transfer of calls from one endpoint to another. During a call transfer, SIP establishes a session between the transferee and a new endpoint (specified by the transferring party). SIP also terminates the session between the transferee and the transferring party. At the end of a call, SIP terminates the sessions between all parties. Conferences can consist of two or more users and can be established using multicast or multiple unicast sessions. SIP Components SIP is a peer-to-peer protocol. The peers in a session are called User Agents (UAs). A user agent can function in one of these roles: User agent client (UAC) A client application that initiates the SIP request. User agent server (UAS) A server application that contacts the user when a SIP request is received and returns a response on behalf of the user. 2

9 Cisco ATA 191 Analog Telephone Adapter Overview Session Initiation Protocol Typically, a SIP endpoint is capable of functioning as both a UAC and a UAS, but functions only as one or the other per transaction. Whether the endpoint functions as a UAC or a UAS depends on the UA that initiated the request. From an architectural standpoint, the physical components of a SIP network can also be grouped into two categories Clients and servers. The following figure shows the architecture of a SIP network. Note SIP servers can interact with other application services, such as Lightweight Directory Access Protocol (LDAP) servers, a database application, or an extensible markup language (XML) application. These application services provide back-end services such as directory, authentication, and billable services. Figure 2: SIP Architecture SIP Clients SIP clients include: Gateways Provide call control. Gateways provide many services, the most common being a translation function between SIP conferencing endpoints and other terminal types. This function includes translation between transmission formats and between communications procedures. In addition, the gateway also translates between audio and video codecs and performs call setup and clearing on both the LAN side and the switched-circuit network side. Phones Can act as either a UAS or UAC. The ATA 191 can initiate SIP requests and respond to requests. SIP Servers SIP servers include: 3

10 Cisco ATA 191 Hardware Cisco ATA 191 Analog Telephone Adapter Overview Proxy server The proxy server is an intermediate device that receives SIP requests from a client and then forwards the requests on the client s behalf. Proxy servers receive SIP messages and forward them to the next SIP server in the network. Proxy servers can provide functions such as authentication, authorization, network access control, routing, reliable request retransmission, and security. Redirect server Receives SIP requests, strips out the address in the request, checks its address tables for any other addresses that may be mapped to the address in the request, and then returns the results of the address mapping to the client. Redirect servers provide the client with information about the next hop or hops that a message should take, then the client contacts the next hop server or UAS directly. Registrar server Processes requests from UACs for registration of their current location. Registrar servers are often colocated with a redirect or proxy server. Cisco ATA 191 Hardware The ATA 191 is a compact, easy to install device. The following figures show the top and rear panels of the ATA 191. The unit provides these connectors: 5V DC power connector. Two RJ-11 FXS (Foreign Exchange Station) ports The ATA 191 supports two independent RJ-11 phone ports that can connect to any standard analog phone device. Each port supports either voice calls or fax sessions, and both ports can be used simultaneously. The ATA 191 has one WAN network port An RJ-45 10/100BASE-T data port to connect an Ethernet-capable device, such as a computer, to the network. You connect to the network switch or a computer running Cisco Unified Communications Manager using this port. Note The ATA network port performs autonegotiation for duplex and speed. It supports speeds of 10/100 Mbps and full-duplex. 4

Fax Passthrough Name Signaling Event (NSE) -based and re-invite-based passthrough provide transport of fax communications using the G.711a/u codec. Transport Layer Security Protocol Transport Layer Security (TLS) is a cryptographic protocol that secures data communications such as on the Internet. TLS is functionally equivalent to Secure Sockets Layer (SSL). T.38 Fax Relay The T.38 fax relay feature enables devices to use fax machines to send files over the IP network. In general, when a fax is received, it is converted to an image, then sent to the T.38 fax device. When the target T.38 fax device receives this image, the device converts the image back to an analog fax signal. T.38 fax relays configured with voice gateways decode or demodulate the fax signals before they are transported over IP. With the SIP call control protocol, the Session Description Protocol (SDP) entries in the initial SIP INVITE message indicate that T.38 fax relay is present. After the initial SIP INVITE message, the call is established to switch from voice mode to T.38 mode. Cisco Unified Communications Administration allows you to configure a SIP profile that supports T.38 fax communication. The ATA 191 only supports T38 Fax Relay Version 0 (G3). Supported Voice Codecs The ATA 191 supports these voice codecs: G.711 mu-law G.711 A-law 8

T.38 Fax Relay mode: The T.38 fax relay feature enables devices to use fax machines to send files over the IP network. In general, when a fax is received, it is converted to an image, then sent to the T.38 fax device. When the target T.38 fax device receives this image, the device converts the image back to an analog fax signal. T.38 fax relays configured with voice gateways decode or demodulate the fax signals before they are transported over IP. Note Success of fax transmission depends on network conditions and fax modem response to these conditions. The network must have reasonably low network jitter, network delay, and packet loss rate.

To provide this capability, the ATA 191 depends upon and interacts with several other key Cisco Unified IP Telephony and Network components, including Cisco Unified Communications Manager, DNS and DHCP servers, TFTP servers, media resources, and so on. To function in the IP telephony network, the ATA 191 must be connected to a networking device, such as a Cisco Catalyst switch. You must also register the ATA 191 with a Cisco Unified Communications Manager system before you can send and receive calls. For related information about voice and IP communications, see this URL: Interaction with Cisco Unified Communications Manager Cisco Unified Communciations Manager is an open industry-standard call process system. Cisco Unified Communications Manager software sets up and tears down calls between analog phones that are connected to the ATA, and thus integrates traditional PBX functionality with the corporate IP network. Cisco Unified 15

22 Power Guidelines Prepare to Install the ATA 191 on Your Network Communications Manager manages the components of the IP telephony system: the phones, the access gateways, and the resources necessary for features such as call conferencing and route planning. Cisco Unified Communications Manager also provides: Firmware for devices Authentication and encryption (if configured for the telephony system) Configuration and CTL files via the TFTP service Phone registration Call preservation, so that a media session continues if signaling is lost between the primary Communications Manager For information about configuring Cisco Unified Communications Manager to work with the IP devices described in this chapter, see Administration Guide for Cisco Unified Communications Manager and IM and Presence Service, System Configuration Guide for Cisco Unified Communications Manager, and Security Guide for Cisco Unified Communications Manager. Power Guidelines The ATA is powered with external power. External power is provided through a separate power supply. The following power type and guideline applies to external power for the ATA: Power Type External power (provided through the Universal AC external power supply). Guidelines The ATA uses the Universal AC power supply 100/240V. Related Topics Electrical Specifications, on page 56 Power Outage Your accessibility to emergency service through the phone depends the phone being powered. If there is an interruption in the power supply, Service and Emergency Calling Service dialing will not function until power is restored. In the case of a power failure or disruption, you may need to reset or reconfigure equipment before using the Service or Emergency Calling Service dialing. Phone Configuration Files Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco Unified Communications Manager. When you make a change in Cisco Unified Communications Manager that requires the ATA 191 line to be reset, the phone configuration file is automatically updated. If a system reset or restart is required, both lines must reset or restart at the same time. Configuration files also contain information about which image load the ATA 191 should be running. If this image load differs from the one currently loaded on an ATA 191, the phone contacts the TFTP server to request the required load files. These files are digitally signed to ensure the authenticity of the file source. 16

23 Prepare to Install the ATA 191 on Your Network ATA 191 Startup Process If the device security mode in the configuration file is set to Authenticated and the CTL file on the ATA 191 has a valid certificate for Cisco Unified Communications Manager, the phone establishes a TLS connection to Cisco Unified Communications Manager. Otherwise, the ATA 191 establishes a TCP/UDP connection. You can go to Voice > Line > SIP Settings on the ATA 191 web GUI, where the SIP Transport should correspond to the transport type in the Phone Security Profile in Cisco Unified Communications Manager. If you configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file contains sensitive information. To ensure the privacy of a configuration file, configure it for encryption. For detailed information, see the Encrypted Phone Configuration Setup chapter of the Security Guide for Cisco Unified Communications Manager at: unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-list.html. If the ATA 191 has registered before, the ATA 191 accesses the configuration file named ATA<mac_address>.cnf.xml, where mac_address is the MAC address of the phone. If the ATA 191 cannot access that configuration file, then it accesses the default XMLDefault.cnf.xml configuration file. If autoregistration is not enabled and you did not add the ATA 191 to the Cisco Unified Communications Manager database, the ATA 191 does not attempt to register with Cisco Unified Communications Manager. For the ATA 191, the TFTP server generates these SIP configuration files: SIP IP Phone: For unsigned and unencrypted files ATA<mac>.cnf.xml For signed files ATA<mac>.cnf.xml.sgn For signed and encrypted files ATA<mac>.cnf.xml.enc.sgn The filenames are derived from the MAC Address in the Phone Configuration window of Cisco Unified Communications Manager Administration. The MAC address uniquely identifies the phone. For more information, see the Administration Guide for Cisco Unified Communications Manager and IM and Presence Service. For more information about how the phone interacts with the TFTP server, see the Configure TFTP Servers chapter of the System Configuration Guide for Cisco Unified Communications Manager at: products-installation-and-configuration-guides-list.html ATA 191 Startup Process When the ATA 191 connects to the VoIP network, it goes through a standard startup process. Depending on your specific network configuration, not all these process steps may occur on your ATA. Table 3: ATA 191 Startup Process Task 1 Obtaining power. The ATA 191 uses external power. Related Topics See Power Guidelines, on page

24 ATA 191 Startup Process Prepare to Install the ATA 191 on Your Network Task Loading the Stored Image. The Cisco ATA 191 has nonvolatile flash memory in which it stores firmware images and user-defined preferences. At startup, the ATA 191 runs a bootstrap loader that loads an ATA 191 image stored in flash memory. Using this image, the ATA 191 initializes its software and hardware. Obtaining an IP Address. If the Cisco ATA 191 is using DHCP to obtain an IP address, the device queries the DHCP server to obtain one. If you are not using DHCP in your network, assign static IP addresses to each device locally. Requesting the CTL file. The TFTP server stores the CTL file. This file contains the certificates necessary for establishing a secure connection between the device and Cisco Unified Communications Manager. Requesting the Configuration File. The TFTP server has configuration files, which define parameters for connecting to Cisco Unified Communications Manager and other information for the ATA 191. Contacting Cisco Unified Communications Manager. The configuration file defines how the ATA 191 communicates with Cisco Unified Communications Manager and provides a device with its load ID. After obtaining the file from the TFTP server, the device attempts to make a connection to the highest priority Cisco Unified Communications Manager on the list. If the device is configured for secure signaling (encrypted or authenticated), and the Cisco Unified Communications Manager is set to Mixed (security) mode, the device makes a TLS connection. Otherwise, it makes a nonsecure TCP/UDP connection.

See Phone Configuration Files, on page

25 Prepare to Install the ATA 191 on Your Network Start up Process with Standby Image Start up Process with Standby Image The ATA 191 has two images or partitions in permanent storage. The second image allows the device to recover if the initial image is corrupted. Press the PRT button when the power is on, and you switch to the standby partition. Startup is similar to the normal process, except that the LED for Phone 2 flashes amber indicating that the second partition is being used. Related Topics Startup Process Verification, on page 23 Addition of the ATA 191 to the Cisco Unified CM Database Before you install the ATA 191, choose a method for adding the devices to the Cisco Unified Communications Manager database. The following table provides an overview of these methods for adding the ATA 191 to the Cisco Unified Communications Manager database. Table 4: Add the ATA to the Cisco Unified Communications Manager Database Method Autoregistration Using the Cisco Unified Communications Manager Administration Requires MAC Address? No Yes Notes Results in automatic assignment of directory numbers. Not available when mixed mode is enabled. Requires phones to be added individually. Addition with Autoregistration By enabling autoregistration before you begin installing the ATA 191, you can: Automatically add devices without first gathering MAC addresses from the ATA 191. Automatically add an ATA 191 to the Cisco Unified Communications Manager database when you physically connect the phone to your IP telephony network. During autoregistration, Cisco Unified Communications Manager assigns the next available sequential directory number to the phone. To change any settings, quickly enter devices into the Cisco Unified Communications Manager database and modify settings, such as directory numbers, from Cisco Unified Communications Manager. Move autoregistered devices to new locations and assign them to different device pools without affecting their directory numbers. 19

26 Addition with Cisco Unified Communications Manager Administration Prepare to Install the ATA 191 on Your Network Note Support exists for autoregistration for several devices in the Unified CM at the same time. Autoregistration is disabled by default. Sometimes, you may not want to use autoregistration. For example, if you want to assign a specific directory number to the phone or if you plan to use secure connection with Cisco Unified Communications Manager. For information about enabling autoregistration, see the Enabling Auto-Registration in the Cisco Unified Communications Manager Administration Guide. Note For mixed mode, autoregistration is automatically disabled and cannot be changed. For nonsecure mode, autoregistration is disabled by default but can be enabled manually. Addition with Cisco Unified Communications Manager Administration You can add the ATA 191 individually to the Cisco Unified Communications Manager database using Cisco Unified Communications Manager Administration. To do so, first obtain the MAC address for each device. After you have collected MAC addresses, in Cisco Unified Communications Manager Administration, choose Device > Phone and click Add New to begin. Note The ATA 191 has two FXS ports, and each port has its own MAC address. The first ATA 191 port uses the MAC address and the second ATA 191 port uses the shifted MAC address (example, AABBCCDDEEFF to BBCCDDEEFF01). You can add two devices (either an analog phone or a fax machine) from the Unified CM administration page. For complete instructions and conceptual information about Cisco Unified Communications Manager, see the Cisco Unified Communications Manager Administration Guide and the Cisco Unified Communications Manager System Guide. Determine the MAC Address of the ATA Procedure Choose one of the following methods to determine the MAC address: Look at the MAC label on the back of the ATA. Go to Voice > Information on the web page of the device and check the MAC address. 20

28 Safety Recommendations Install the ATA 191 Safety Recommendations To ensure general safety, follow these guidelines: Do not get this product wet or pour liquids into this device. Do not open or disassemble this product. Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. Use only the power supply that comes with the ATA. Ultimate disposal of this product should be handled according to all national laws and regulations. Read the installation instructions before you connect the system to its power source. The plug-socket combination must always be accessible because it serves as the main disconnecting device. Do not work on the system or connect or disconnect cables during periods of lightning activity. To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. For translated warnings, see the Regulatory Compliance and Safety Information for the Cisco ATA 191 document. Package Contents The ATA 191 package contains the following items: Cisco ATA 191 Analog Telephone Adapter Regulatory Compliance and Safety Information for the ATA 191 5V power adapter with appropriate country clip Ethernet cable Note The ATA is intended for use only with the 5V DC power adapter that comes with the unit. Install Your Cisco ATA You can use either Category 3/5/5e/6 cabling for 10-Mbps connections, but you must use Category 5/5e/6 for 100-Mbps connections. 22

29 Install the ATA 191 Attach a Phone to the ATA 191 Procedure Step 1 Step 2 Connect the power supply to the Cisco DC Adapter port. Connect a straight-through Ethernet cable from the network to the network port on the ATA. Each ATA ships with one Ethernet cable in the box. Attach a Phone to the ATA 191 Before You Begin You can attach one or two phones to an ATA 191. Procedure Connect one or more phones to a phone port of the ATA with an RJ11 cable. The PHONE1 and PHONE2 LEDs on the ATA light as solid green when there is activity on that port. Startup Process Verification After your ATA has power connected to it, it begins the startup process by cycling through these steps: 1 The Power LED flashes during the startup process. 2 The Problem Report Tool (PRT) LED lights solid amber during initial bootup. The LED then flashes amber and then green while the application and kernel are booting. If the PRT LED lights red during bootup, then either the MIC certificate failed, or the ATA failed to obtain a network address. 3 The LED for Phone 1 flashes while the Phone1 port boots, followed by the LED for Phone 2. After the Phone1 and Phone2 ports register with Cisco Unified CM successfully, the corresponding LEDs are lit with solid green. If a phone port fails to register, the LED rapidly flashes in green three times, then repeats. 4 When the ATA has successfully booted, the Power LED lights solid green and the PRT LED turns off. The Network LED flashes as traffic is detected. When you go offhook on the phone, the phone LED begins to flash, and you hear the dial tone. The ATA has completed the startup process.
