Avaya IP Office SIP Trunk Setup

Configuration in Avaya IP Office is only necessary to set up a SIP trunk if you're using SIP Activator. SIP Activator allows notifications to be triggered by dialing a SIP line extension number from any supported Avaya phone on the network, which triggers sending the notification(s) assigned to the SIP line.

Important: SIP Activator is required in order to trigger live broadcast/paging notifications.

There are two main steps:

  • Verify your SIP Trunk Channels license is valid.
    Go to License > SIP Trunk Channel and verify Status is Valid.
  • Obtain your LAN IP address.
    Go System > LAN1 > LAN Settings to get the IP Address.

    • Note: IP Office allows SIP Trunks on LAN1 and/or LAN2.

There are five basic steps:

  1. Click IP Office > System.
  2. Click the LAN1 tab > VoIP tab.
  3. Verify the following are enabled (checked):
    • H323 Gatekeeper Enable
    • Auto-create Extn
    • SIP Trunks Enable
    • SIP Registrar Enable
    • Auto-create Extn/User
    • UDP
    • TCP
    • Enable RTCP Monitoring on Port 5005
  4. Click OK.

There are two parts to configure:

  1. Right-click IP Office > Short Code and select New.
  2. Enter a number and an N variable in the Code field, for example 610N;. The number of N variable(s) you use determines how many SIP lines are available:
    • 610N; – This means you can enter SIP lines in Revolution that range from 6100-6109. You get 10 SIP lines.
    • 61NN; – This means you can enter SIP lines in Revolution that range from 6100-6199. You get 100 SIP lines.
    • If you need 20 SIP lines, create two new short codes:
      • 615N; – This gives you SIP lines 6150-6159. First 10 SIP lines.
      • 616N; – This gives you SIP lines 6160-6169. Second 10 SIP lines.
  3. Select Dial from the Feature drop-down list.
  4. Type a period in the Telephone Number field. (This allows the system to match any number.)

  4. Click OK.

Summary of Network Topology tab

Create SIP lines in Revolution SIP module for the extensions you designated in IP Office. In our example, we're using 610N for the short code, which sets the SIP line range. So, in Revolution, I'll create SIP Lines for 6100-6109. See SIP Activator.

Assign SIP activators and lines as notification triggers. Review the Notifications Basics topic.
