Hello George,

The patches appears to work fine,  the phone no longer causes asterisk to crash.

One minor thing though, asterisk seems to 'accept' the endpoint as a Contact via UDP then immediately remove it from the AOR listing, causing the phone to think it successfully registered.

   -- Added contact 'sip:3202@10.21.16.102:5060;transport=udp' to AOR '3202' with expiration of 3600 seconds
 == Contact 3202/sip:3202@10.21.16.102:5060;transport=udp has been created
 == Endpoint 3202 is now Reachable
   -- Contact 3202/sip:3202@10.21.16.102:5060;transport=udp is now Unreachable.  RTT: 0.000 msec
 == Endpoint 3202 is now Unreachable
