System Networking Lab Table 1 In this diagram each system operates independently to supply network services to the phones on its LAN interface. The phones are powered by a Power over Ethernet switch. The WAN ports are plugged into a switch so they can communicate over a Layer 2 network so there is no need to route between subnets Each system operates in Gateway/Firewall mode in order to NAT each systems LAN to each WAN interface The NAT option allows each system to provide DHCP on each phone subnet to simplify configuration Each system listens on both interfaces for VoIP traffic using the built in SBC (Session Border Controller) The network and dial plans must be built in order to route VoIP traffic between system extensions Each system has a unique Site Prefix in order steer VoIP traffic to each fully qualified host name Incoming calls will have the Site Prefix added to CLID on ingress to make a callback easier Hostname WAN address LAN address DNS Server Ext Prefix Site Prefix Firewall Mode 1000.scopserv.local 192.168.100.1/24 172.16.1.1/16 172.16.1.1 1XXX 801 Gateway/Firewall 2000.scopserv.local 192.168.100.2/24 172.16.2.1/16 172.16.2.1 2XXX 802 Gateway/Firewall 3000.scopserv.local 192.168.100.3/24 172.16.3.1/16 172.16.3.1 3XXX 803 Gateway/Firewall 4000.scopserv.local 192.168.100.4/24 172.16.4.1/16 172.16.4.1 4XXX 804 Gateway/Firewall 5000.scopserv.local 192.168.100.5/24 172.16.5.1/16 172.16.5.1 5XXX 805 Gateway/Firewall 6000.scopserv.local 192.168.100.6/24 172.16.6.1/16 172.16.6.1 6XXX 806 Gateway/Firewall 1000.scopserv.local 1XXX 6000.scopserv.local 6XXX 2000.scopserv.local 2XXX WAN 5000.scopserv.local 5XXX 3000.scopserv.local 3XXX 4000.scopserv.local 4XXX
Network Module - ifconfig A newly installed server uses DHCP to get an IP address from a DHCP server on the network so make sure the eth0 interface is connected to the network so the server can get an IP address. Before you can login to the server you must know the IP address of at least one physical interface. From the Linux console login prompt, enter username root omitting any quotation marks. From the password prompt enter the default root password scopserv omitting any quotation marks. Once you are successfully logged as root type the command ifconfig to determine at least one eth interface. In this example the eth0 IP address is 192.168.192.60 Also notice that the HWaddr is the MAC address of the eth0 interface.
Network Module system-config-network If there is no DHCP server on the network the server will not get an IP address. Using the command system-config-network omitting any quotes an IP address can be set statically and then used to login to the GUI.
Network Module system-config-network Use the tab key on the keyboard to select Edit Devices Use the tab key on the keyboard to select eth0 and press enter
Network Module system-config-network Use the tab key on the keyboard to select elements. Use the space bar to uncheck or check DHCP. Use the keyboard to enter a Static IP and Netmask for this local server as in this example using the IP address table from the System Networking Lab Table 1 Use the tab key to select Ok. Press Enter when finished.
Network Module system-config-network Use the tab key on the keyboard to select Save Press Enter when finished Use the tab key on the keyboard to select Save&Quit Press Enter when finished
Server Module service network restart From the root prompt type service network restart omitting any quotes to restart the network with the new static IP address.
Network Module Web GUI Login Once logged into the GUI the eth1 interface must be configured in order to enable routing. The ifconfig command displays the MAC address of eth1 which is needed to add another network interface to the system. The eth1 MAC address in this example is 00:E0:81:D8:5D:BD.
Network Module Web GUI Login Open a web browser and use the IP address found using the ifconfig command in the following format: http://<ip address>:5555 Where <ip address> if the IP address of the server and the :5555 is the listening port of the ScopTEL web server. Example: http://172.16.1.1:5555 The default login username is admin omitting quotes. The default admin password is admin omitting any quotes.
Server Module Configuration Wizard Since each system is a new install after the first admin login you will be prompted to run the ScopServ Initial Server Configuration Wizard.

Network Configuration Network Interfaces On a new installation it may be necessary to add an eth1 interface in order to configure the WAN interface. From the Configuration>Network>Interfaces tree check to see if both eth0 and eth1 interfaces already exist. If the eth1 interface is already configured then from the Configuration>Network>Interfaces tree click on edit eth1. If the eth1 interface is not configured, then from the Configuration>Network>Interfaces tree click on Add a new Interface.
Network Configuration WAN Interface In this example the eth1 configuration from the lab exercise system is 1000.scopserv.local and the eth1 WAN interface is 192.168.100.1/24. Substitute the IP address and subnet mask and MAC address for the system you are working on using the information table on page 1. When finished click Add or Save depending on whether you must add eth1 or it is already configured.
Network Configuration LAN Interface In this example the eth0 configuration from the lab exercise system is 1000.scopserv.local and the eth0 LAN interface is 172.16.1.1/16. Edit the eth0 interface and substitute the IP address and subnet mask and MAC address for the system you are working on using the information table on page 1. When finished click on Save.
Network Configuration Hostname In this example the hostname configuration from the lab exercise system is 1000.scopserv.local and you will use the eth0 LAN address as the DNS server address which is also the DNS Server information from page 1. Edit the default Hostname and when finished click on Save.

Network Configuration DHCP Subnet Table 3 Use this table to create the DHCP server configuration for each system on the network. Note that each scope belongs to a class B subnet so it can service more than 254 IP addresses. In real scenarios a larger subnet might be necessary to provide DHCP to thousands of IP phones. The Default Gateway belongs to the LAN address of each server so the DHCP client will NAT outbound to reach subnets that are not local. Primary DNS is the local server which is configured with A records for each other server. The TFTP server for each subnet is the LAN address of the local server which will use the Automatic Provisioning System to manage the configuration files for each IP Phone. The NTP server for each subnet is the LAN address of the local server and the local server will act as a Network Time Protocol (NTP) server on each local subnet. hostname DHCP Start DHCP Stop Default Gateway Primary DNS Domain Name TFTP Server Name NTP Server Time Offset 1000.scopserv.local 172.16.1.100 172.16.2.254 172.16.1.1 172.16.1.1 scopserv.local 1000.scopserv.local 1000.scopserv.local -18000 2000.scopserv.local 172.16.3.100 172.16.4.254 172.16.2.1 172.16.2.1 scopserv.local 2000.scopserv.local 2000.scopserv.local -18000 3000.scopserv.local 172.16.5.100 172.16.6.254 172.16.3.1 172.16.3.1 scopserv.local 3000.scopserv.local 3000.scopserv.local -18000 4000.scopserv.local 172.16.7.100 172.16.8.254 172.16.4.1 172.16.4.1 scopserv.local 4000.scopserv.local 4000.scopserv.local -18000 5000.scopserv.local 172.16.9.100 172.16.10.254 172.16.5.1 172.16.5.1 scopserv.local 5000.scopserv.local 5000.scopserv.local -18000 6000.scopserv.local 172.16.11.100 172.16.12.254 172.16.6.1 172.16.6.1 scopserv.local 6000.scopserv.local 6000.scopserv.local -18000

Telephony Module Outgoing Lines Dial Plan Summary An Outgoing Line for each remote server must be built for each local server based on the Outgoing Line Dial Plan Table 17-22. The Outgoing Line Custom Dial Plan determines which VoIP Interface to use by recognizing digits dialed to steer the call to the desired server. For example when the digits dialed from system 1000.scopserv.local are 8022001 the server recognizes 802 as the prefix for the 801to802 VoIP Interface and passes 2001 to server 2000.scopserv.local. 2000.scopserv.local then matches the incoming digits 2001 to local extension 2001 causing the phone to ring. The same rules remain true for any VoIP (SIP, IAX2, Skinny) or TDM (ISDN PRI) trunk that supports DNIS routing. Here is the configured Outgoing Lines summary for 1000.scopserv.local.
Telephony Module Outgoing Lines Dial Plan Configuration Click Add a New Outgoing Line. Give the Outgoing Line an alphanumeric name (no upper case or special characters). Select the correct outgoing Trunk that matches the dial plan. When done Click on the Dial String tab.
Telephony Module Outgoing Lines Dial Plan Configuration Choose Type Custom Dial String from the drop down list. Since Dial Plans rely on X the Dial String includes the site prefix and the wild card upper case XXXX. Number of digit to strip 3 strips the first 3 digits from the outgoing call sending only the last 4 digits allowing the remote server to do a dial plan lookup and steer the call to a matching extension using the Incoming Lines Dial Plan. When done click on the Dial Options tab and use the Outgoing Line Dial Plan Table 17-22. Note that the Dial Options are common for each server. When done Click Add.
Telephony Module Manager>Class of Service default Newly installed 2.5 systems include all Outgoing Lines in the default Class of Service for all tenants. You should check the Class of Service to make sure each newly created Outgoing Line is allowed for the Class of Service assigned to each extension. Add a new Class if you need to create a custom Class of Service.
Telephony Module Security SIP Phones are SIP User Agents. For security, SIP User Agents must register to the SIP Registrar via username and password authentication. It is typical for the SIP protocol ports to be open or forwarded to the ScopTEL server if a third party Firewall is implemented. When the SIP ports are exposed on the Firewall it is common for hackers to attempt brute force attacks on the server. Such attacks systematically request authentication using common dial plan Extensions and trivial passwords. Examples of such brute force attacks: Extension range 1000-3000 Systematic Password attempts using passwords 1000-3000 Systematic Password attempts using passwords 0000, 1234, 1111, 4321, 123456, 7654321 Therefore if a secure password policy is used it will prevent the overall majority of hackers from registering a SIP Extension or SIP Trunk with the server for fraudulent purposes. Examples of secure SIP password policy Minimum password length of 8 alpha numeric characters. No Dictionary words Minimum 2 Upper Case characters used Minimum 2 numerals used Passwords should be unique for each extension The same policy enforcement should be in effect when configuring Voicemail Passwords except Voicemail Passwords cannot contain Alpha characters and must be numeric. A poorly implemented Voicemail Password Policy can allow a hacker access to thru dial capabilities from a mailbox configured to allow outdial capabilities. Therefore Voicemail Passwords must be strict regardless of inconvenience caused to end users. Voicemail Password should never match the extension number. Example: Extension 100, Voicemail Password 100 Voicemail Password should never be trivial. Examples: 0000, 1234, 1111, 4321, 123456, 7654321
Telephony Module Security Here are the recommended Settings. To set a Global Password Security Policy navigate to Configuration>Telephony>Configuration>Security. The SIP and IAX2 Password Policy is set independently of the Global Voicemail Password Policy. If the Options to automatically fix invalid password?[x] is checked then non-compliant passwords will be made compliant after a commit (recommended).
Telephony Module Extensions Typical Extensions types are: SIP Extension (IP Extension using the SIP protocol) IAX2 Extension (IP Extension using the IAX2 protocol) Zap Extension (analog FXS extension using Sangoma or Digium cards. Sangoma and Digium cards should not coexist in the same server) Voicemail Extension (Voicemail box only) HotDesk Extension A HotDesk Extension is an Extension that logs into a physical Extension using the HotDesk Feture Code, HotDesk Extension number and required password. By logging into a physical Extension the HotDesk Extension can make and receive calls from any extension which allows the HotDesk Feature Code in its assigned Class of Service. Caller ID incoming and outgoing will be automatically manipulated to display HotDesk user information. Virtual Extension A Virtual Extension is a very advanced Extension type which allows a user to login to the ScopTel GUI and use the Realtime Monitor and customize Call Detail Reports and other types of reports. Advanced options can be configured to ring multiple destinations and automatically forward copies of voicemail messages to multiple extensions User Options for Virtual Extensions include Follow Me, Camp-On, Personal IVR destinations Custom Forwarding Rules can be defined for: Call Forward Immediate Call Forward Busy Call Forward No Answer Call Forward Unavailable (forward when physical extension is offline) It is possible to Immediate Forward a Virtual Extension to make an Application available within an IVR context for inbound PSTN callers.
