HKBN 2b Call Drop with SIP Error 481

I am opening a new thread in Bugs because I believe this is a bug in the software.

The problem is that the call will get dropped after approximately 7-10 minutes with a SIP Response 481. This problem is back sometime late last year and after trying various methods including getting a PRO account and modify the source, Perhaps when Asterisk was upgraded the patch was overwritten?
