Summary:                    error on SIP INVITE when host's external IP changes
Description: 
I have got 2 Asterisk boxes connected to each other via Internet (both are
behind NAT). One have static IP (A), other is dynamic (B). Dynamic
registers to static respectively. Other client C is connected to B and
placing a call via B to A.  So when public IP of host B changes, I cannot
place calls using client C, from B to A, until Asterisk A is being
rebooted. dnsmgr is enabled. when i tracert to host B, i see the correct IP
address, as above in SIP headers.

some logs...
