we need to see your sip.conf.

We also need to know what implementation of NAT that you're using.  Some implementations don't do a very good job of permitting persistent connections.

Based on a talk on IRC with vechers I do not believe your bug belongs here. It is clearly a configuration issue and not an Asterisk bug. Please look into the sample sip.conf in regards to options about NAT such as externip/externhost/localnet/nat/canreinvite. If you require further help post to the asterisk-users mailing list. Have a great day! PEACE!
