Avaya IP Office SIP Trunk ConfigurationGuideValcom Session Initiation Protocol (SIP) VIP devices are compatible with SIP-enabled versions of Avaya IP Office (5.0and higher). The Valcom device can be added to the IP Office system as a SIP Trunk. Valcom devices with multiple SIPchannels may be configured in a one-to-many arrangement, where one Avaya SIP Trunk Channel can service multipleSIP identities on a single Valcom device. Call routing will be determined using Short Codes. Each Avaya SIP TrunkChannel instance allows one concurrent call over the IP connection.These instructions cover the minimum configuration necessary for a Valcom SIP-enabled device. Refer to Avayadocumentation for details on SIP services and entering SIP Trunk Channel License information. Other settings may alsobe necessary, depending on your specific system environment.The following steps outline the typical configuration process:1. Open the Avaya IP Office Manager application and connect to the IP Office server where the new SIP trunk willbe created. In the Navigation pane, click on the Line category.2. Click the New iconin the upper-right corner of the Details pane, and choose SIP Line to open a new Detailspane. In the Line Number field, accept the default or enter a new number. In the ITSP IP Address field, enter theIP address of the Valcom device that will be the destination for calls on this trunk. Set the Layer 4 Protocolselection to UDP.For this example, SIP Line 9 is being created and will send calls to IP address 192.168.96.237. The protocol willbe UDP and will connect to port 5060 on the Valcom device.03/24/2010Page 1 of 7

Avaya IP Office SIP Trunk ConfigurationGuide5. In the Navigation pane, click on the Short Code category. For this example, the Valcom VIP-201 Paging Server isbeing configured as the trunk endpoint. The VIP-201 has 8 SIP identities (phone numbers), which will beconfigured as extensions 5801 through 5808. A Short Code will be defined to route calls to those destinationnumbers over the SIP Line (trunk) created in the previous steps.6.Click the New iconin the upper right corner of the Details pane to create a new Short Code. In the Detailspane, enter a code that will match the dial code used in your system. For our example, the Valcom VIP-201 willbe configured with phone numbers 5801 – 5808, so the Code will be entered as “580X;”. Select “Dial” for theFeature. The Telephone Number to send will be 580N”@192.168.96.237”, and the Line Group ID used will be theSIP Line created in previous steps (9, in this example).03/24/2010Page 3 of 7

Avaya IP Office SIP Trunk ConfigurationGuide11. The Valcom SIP device must now be programmed with the settings used on the IP Office server, using the VIP102B IP Solutions Setup Tool.Note: The information contained in this guide is limited to configuration of the “SIP” tab in the VIP-102B IPSolutions Setup Tool for the Valcom device. More information on Valcom VIP device configuration, such as IPaddress assignment, relay activation, etc, may be found in the VIP-102B Reference Manual. This document maybe downloaded from our website at http://www.valcom.comRequired Fields: Phone Number, SIP Server, SIP Server Port, SIP Port, RTP PortIn our example, the Valcom VIP-201 Page Server is the device that will be connected via SIP trunk to the IPOffice server. The VIP-201 has 8 SIP Phone Numbers available. The Phone Number shown for this example(5801) is within the range of numbers IP Office will route to the SIP Line. The other 7 SIP Identities would besimilarly configured with Phone Numbers that will be routed by IP Office to the same SIP Line (5802, 5803, etc).SIP Server is the address of the Avaya IP Office, “192.168.97.60”, and the Register box is not checked.SIP Server Port is the port number on which the Avaya IP Office SIP server is listening for SIP data. SIP Port isthe port number on which the Valcom device is listening for SIP data. By default, both SIP ports are set to “5060”.RTP Port is the port number on which the Valcom device will send/receive audio packets. Default is “20000”.03/24/2010Page 6 of 7

The new configuration will be copied to the Valcom device, and you will be prompted toreset the device for the changes to become effective. Allow the device to reset before continuing.13. With both the IP Office configuration and the Valcom device configuration completed, the success of theconfiguration may be checked using the Avaya System Status application. Expand the Trunks section, then clickthe Line corresponding to the SIP Line that was created previously. The Trunk Summary will be displayed asshown in the example below.03/24/2010Page 7 of 7
