6 6 1 Preface 1.1 Audience This document is intended for GENBAND s QFlex technical staff and any individual tasked with the integration of GENBAND s QFlex enterprise SBC with a Cisco Unified Communications Manager (CUCM) and XO Communication s SIP Trunking service. 1.2 Introduction Configuration Guides are written to provide a system integrator the necessary information to construct an integration similar to what has been built for certification or IOT purposes. This document s focus is on the certification of the GENBAND QFlex SBC along with Cisco Unified Communications Manager (CUCM) version 10 with XO Communication s SIP Trunking service. The reference architecture is shown in Figure Configuration Data The configuration data provided within is shown in graphic user interface (GUI) format where possible. The appropriate data values are shown graphically, largely in their default values. Comments will be provided alongside many GUIs to enforce/explain various parameter values to be provisioned. Some configuration will be provided in command line interface where applicable. 1.4 System Integration Caveats and Notes Caveats Caller ID on a call transfer target device in the PSTN shows the transferor ID, not the transferee. Observed in both ringing and consultative call transfers. Configuration Notes For full compliance of T.38 test cases, XO s network was configured to force fax calls to T.38. Note that G.711 fax works in this test environment when XO s network is configured for G.711 Fax / T.38 Fax. REFER-based call transfer requests from CUCM are not supported by QFlex. All Call Transfer functionality passed using INVITE-based call transfer method.

46 46 Configure Call Forwarding targets in Destination field. Options for differentiated CF exists based on caller being internal CUCM extension or external PSTN. If calls are to roll to voice mail, simply check the checkbox under Voice Mail.

47 47

48 48 The Line Text Label value will be shown on the phone s display. Normalize the external caller ID to 10 digits by provisioning the External Phone Number Mask as seen above. The Multiple Call / Call Waiting Settings are shown with their default values. Move the Busy Trigger to 1 to help with Call Forward Busy testing.

49 FAX A CUCM Device is required to represent the SIP/analog IAD gateway placed between CUCM and the analog FAX machine. Add this device by browsing to Device > Gateway. Click the Add New button to add the Gateway device.

50 50 Click the Save icon to commit and bring up additional items for consideration as seen below.

51 51 Click the Save icon to commit and bring up additional items for consideration as seen below. Click on the analog port icon next to the physical port on the IAD that will be used to connect with the FAX machine. In this example, we use port 0/3/0. Select POTS Port Type and hit the Next button to bring up the provisioning interface as seen below.

52 52

53 53 Now add a DN to the gateway configuration to represent the FAX number.

54 54

55 Route Patterns A Route Pattern ties a digit pattern dialed by a CUCM client to SIP trunk connecting CUCM to an external service. Specifically, n digits are reserved by the administrator to be dialed in addition to a target phone number on a remote system. The n digits are referred to as the Route Pattern in CUCM terminology. To configure a Route Pattern, browse to Call Routing > Route/Hunt > Route Pattern and click the Find button to show all existing Routes. Route Pattern to PSTN Create a Route Pattern for users to dial as a prepend to the target phone number. This pattern will point to an outbound route for the call to take over a SIP Trunk. In this IOT, the route pattern 8 was used as seen in the Route Pattern below to steer PSTN calls to the SIP trunk connecting the CUCM to the local QFlex and ultimately to the XO SIP Trunking service.

56 56 In the Route Pattern field, the value indicates that any phone number dialed with a 8 prefix will be routed out the SIP Trunk referenced in the Gateway/Route List field. Set Numbering Plan to NANP. Reference the target SIP Trunk in the Gateway/Route List field.

57 57 The Calling Party Transform Mask should be enabled and defined with six digits to complement the four-digit extension range defined for this IOT. This empowers the CUCM to build an outgoing INVITE message with a 10 digit caller ID value. In the Called Party Transformations window, enter a value of PreDot in the Discard Digits field to trigger CUCM to discard the Route Pattern identifier digit dialed by users making PSTN calls.

58 58 Route Pattern to Cisco Unity Connection Provide a voice mail pilot number in the Route Pattern field. Associate the SIP Trunk which connects CUCM to Cisco Unity Connection in the Gateway/Route List field.

59 59

60 60 4 QFlex Access the QFlex Server via the QFlex Element Management System (EMS) web-based provisioning management interface at IP Address>. QFlex EMS Login with an account that has administrator privileges.

61 Create New Service Configuration Create a new service configuration by selecting Configuration > Service Configuration from the QFlex menu and then clicking on the Create Service Configuration button as seen below. Give the new Service Configuration a descriptive name and click the Create button.

62 62 The default service configuration (previously configured) will appear as seen in the graphic below. Edit this configuration to fit the IOT environment as discussed below.

63 63 Trunk Provisioning Edit LAN Logical Interface Provide the QFlex LAN-side (i.e., PBX side) interface attributes as seen in Figure 3.

64 64 Figure 3 LAN-side Interface Configuration Provide the LAN-side QFlex IP Address in the Address field. Select the physical QFlex Interface which supports the LAN-side connection. Provide the Netmask associated with the assigned IP Address. Click the Update button to save the configuration. Edit WAN Logical Interface Repeat the above procedure for the QFlex WAN-side Logical Interface as seen in Figure 4.

65 65 Figure 4 WAN-side Interface Configuration Now define the Application Interfaces. This is where QFlex is configured with the adjacent nodes IP interfaces information and the mechanisms which govern how the communication is to occur. To edit an application interface, click on the Edit hyperlink as seen in the graphic below.

66 66 Edit LAN Application Interface

67 67 Reference the corresponding Logical Interface as defined earlier for the LAN side. The Mate Application Interface represents the LAN side s paired interface, i.e., the WAN side interface. Select the PBX/Gateway Profile which mostly closely identifies the PBX. Indicate the transport protocol to be used between QFlex and the PBX by specifying the QFlex listen port in the proper protocol field. Values of 0 mean that transport is disabled. In the Network field, select Local Area Network. Add a Next Hops entry for each CUCM node in the CUCM cluster that will be interacting with QFlex. Be sure to check your CUCM cluster setup to understand how many nodes are deployed. Specify the IP Address, Transport Type and Listen port for each PBX node. Note that a value of 0 effectively deactivates a transport type. When finished, click the Update button to save the provisioned data.

68 68 Next, the following Advanced Parameters will be shown for any necessary modification.

69 69

70 70 Edit WAN Application Interface Reference the corresponding Logical Interface as defined earlier for the WAN side. The Mate Application Interface represents the paired interface, i.e., the LAN side interface. Select the PBX/Gateway Profile SIP BroadsoftBW 1 as it best represents the SIP entity within XO s SIP Trunking service. Indicate the transport protocol to be used between QFlex and XO by specifying the QFlex listen port in the proper protocol field. Values of 0 mean that transport is disabled. In the Network field, select Wide Area Network. Add the Next Hop Network info representative of the XO Service as seen below.

71 71 Provide the IP address of the XO Signaling Server in the Address field. Specify the associated XO listen port in the field which represents the transport protocol to be used between QFlex and XO. Note that a value of 0 effectively deactivates a transport type. Click the Add button to add the Next Hop data. Click the Update button (at the bottom of the page) to save the WAN Application Interface data. Next, the following Advanced Parameters will be shown for any necessary modification.

72 72 Set DTMF Type to 2833 Event Packets for RFC 2833 DTMF support across the WAN link. Set this parameter to Audio RTP Packets to force QFlex to use in-band DTMF. Use the Prepend Digits on Diversion Header field to control if and how QFlex prepends digits to Diversion headers within SIP requests received from the LAN side and transmitted to the WAN side. In the CUCM integration with XO, CUCM populates the Diversion header (in use cases such as call forwards to the PSTN) with the CUCM extension value in this case a 4-digit extension. XO requires a 10 digit Diversion header representative of one of its DNs. Hence, this QFlex field is used to augment the received Diversion header to its full 10-digit DN value. PLEASE NOTE: This QFlex normalization

73 73 is global in nature, that is, it s good for one number range. If the enterprise has more than one block of DNs which collectively cannot be represented by a single entry in this QFlex field, then the Diversion normalization must be performed in CUCM using a script which can provide the flexibility to define multiple DN ranges and Diversion header augmentation.

74 74 Trunks Click the Add link next to the Trunks section of the Service Configuration as seen above. This will present the GUI as seen in Figure 5.

75 75 Figure 5 - Trunk Definitions Reference both the WAN and LAN application interfaces created earlier. Declare a DTMF payload ID of 101. Click the Add button to confirm. Now Edit the Trunk as seen in Figure 6. This step allows for further specification of the links to each adjacent network node.

76 76 Figure 6 - Edit Trunk Under Audio Codecs, select the Add link.

77 77 Add both the G.711 ulaw and G.711 alaw codecs and then select the Update button to confirm these settings as seen in Figure 7. Figure 7 - Confirm Codecs Now associate this entire new configuration with a physical QFlex server. Click the associate link as seen in the following graphic.

78 78 Figure 8 - Associate Configuration Click on the Physical QFlex server name representative of the host QFlex server from the available list as seen Figure 9. If no physical servers are shown, enter % in the search field and click the Find button.

82 82 SIP Management Access Configuration > Service Configuration and click on SIP Management as seen in Figure 12. Figure 12 - SIP Management Pilot Number Registration XO Communications does not support esbc registrations, so ensure that QFlex has no Pilot Number configured as seen in the graphic below. The default authorization username, password and refresh rate are auto populated by default but are dormant and can be ignored.

83 83 Session Timers

84 84 QFlex s support of SIP Session Timers can be managed here per the various test case requirements. In the example below, QFlex is the Session Refresher, sending re-invites at 90 second intervals. This refresh interval is a bit short for production environments, but for testing SIP Session Timer usage, it works quite well. Move this value to 1800 seconds once session refresh test case execution is complete.

85 85 Parameters: SIP Management Figure 13 - SIP Management Enable SIP OPTIONS, if need, by providing a value for the SIP Heartbeat Interval field.

86 86 Platform QFLex s internal DNS can be used. To enable this DNS, browse to the Service Configuration and click on the Platform link as seen in Figure 14. Figure 14 - Enable Internal DNS Create a DNS Server with IP address and port as seen below.

87 RTP Relay Configuration Create a new RTP Relay configuration as seen below.

88 88 Interface Pairs Provide the QFlex Public and Private side IP addresses as seen above. The Max Tunnels value must be set to a numeric value which is 10 more than the Call paths value as seen in the QFlex Server configuration found at Server Status > Edit next to your physical QFlex server name. See graphic below with highlighted parameter:

89 89 Control Access
