Initiating an Enterprise Voice call with Lync Server 2013 configured with a SIP trunk to an Avaya PBX generates the error: "Gateway responded with 407 Proxy Authentication Required";component="MediationServer";SipResponseText="Not Acceptable Here"

Problem

You’ve configured a SIP trunk between your Lync Server 2013 and Avaya PBX then proceed to try making a call but it fails.  A trace and review of the snooper logs reveal the following messages:

One of the error messages that catches your eye is the following:

"Gateway responded with 407 Proxy Authentication Required";component="MediationServer";SipResponseText="Not Acceptable Here"

Solution

After troubleshooting the issue with the PBX engineer, we noticed that we actually had a port mismatch between what was configured on his end and what was configured on my end.  The gateway listening port I had configured on my end was set to 5060:

While his end in the Avaya Aura System Manager 6.2 was set to 5068:

Small mistake which was fixed after I changed my TCP port to 5068:

Many educational institutes are working with the aim to bring out the hidden talent of each child, and polish it to such an extent that it would be his distinctive quality which can also serve to be his source of income too.useful site
