Call ended from a Bria 3 softphone and Adtran IP 706 keeps ringing

[#1]

Hi,

We are currently testing Bria 3.4.2 with our NetVanta 7060 PBX and we have a small bug with Adtran IP 706/712 IP phones. Here is how to reproduce the bug :

1. Using the Bria 3 softphone, make an internal call to a Adtran IP 706/712 extension
2. Don't answer the call on the IP 706 and drop the call from the Bria softphone
3. The IP706 keeps ringing even if the call is dropped on the softphone

If you answer the call from the IP 706 and then drop the call in the softphone, the call is dropped correctly on both sides. We don't have this bug with Polycom phones.

The firmware in the IP 706/712 is 1.3.16. Is there anything we can do with Bria 3 to make it compatible with IP 706 phones?

Thanks!
