Noticed that the Alert-Info Header is causing the problem, part of the INVITE message being sent out to AVAYA Phone (Third Party SIP device in my case).

Alert-Info: <file://Bellcore-dr1/>

1. Configured a SIP Normalization Script to remove the Alert-Info Header from the INVITE message.

2. Applied the Normalization script to a SIP Profile.

3. Applied the SIP Profile to the Avaya Phone.

4. Test calls were successful both-sided with proper 2-way audio communication.
