How to configure an AVAYA IP trunk

Our focus in this article is to achieve the connection between your AVAYA server, and our Mission Control Portal. We will describe a sample configuration of the IP trunk and the dialplan assuming that you already made the main AVAYA installation and telecommunication-applications deployment.

Once you have configured the following steps, you can take advantage of leveraging our Mission Control Portal to maximize your business operations.

Your trunk is ready to go on our side! We can move forward with the configurations on your AVAYA PBX. The configurations are shown step-by-step on the subtitles below:

Create a Line:

Under IP Offices/Line add SIP line with the following Configurations:

SIP Line

Line Number: 100 (whichever number you have available)
ITSP Domain Name:
Location: Cloud

In service: Enable
Check OOS: Enable
Refresh Method: Auto
Timer (seconds): On Demand


ITSP Proxy Address:
Layer 4 Protocol: UDP
Send Port: 5060
Use Network Topology Info: LAN 2 (whichever LAN you have configured for SIP trunking)

Add channel with the following configurations:

Via: ( = your public IP)

PAI: *
Registration: 0:  
Incoming Group: 100 (Number added on SIP Line)
Outgoing Group: 100 (Number added on SIP Line)

Dial Plan:

Under IP Offices/Short Code add a Short Code with the following Configurations:

Note: To make outbound calls, Telnyx requires either a valid caller ID from your device or a caller ID override enabled on your SIP connection. Please view our caller ID number policy for information on enabling a caller ID override from within the Telnyx portal.
