I check my log carefully and so far I do find something suspicious. There are in fact two invites being sent out for B, each with a different branch number and almost identical

(1) userB@internal_IP:5060
(2) userB@external_router_IP:5050

When B answers the phone, somehow a CANCEL message is dispatched to cancel the invite sequence for (1). That in itself seems to kill the connection as well. There's no CANCEL message sent for (2) but there's no ACK sent for (2) either so I suppose the act of CANCEL for (1) has killed off (2) for a certain reason.

So far I still have not known exactly why that device behind the router registers twice, once with an internal LAN address and another with an external router IP. But that's not the issue here. Should the CANCEL message for (1) kill off that of (2) as well?
