    Max Calls per Channel: 10

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

    Feature: Dial
    Telephone Number: 1N

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.

That's it! You've now configured an AVAYA IP trunk and connected it to Telnyx!
