Description:The problem happens because Asterisk fills 'Contact' header in SIP-message using remote port number instead local port number.

Example:
REGISTER sip:sip.asterisk.xxx.com:55060 SIP/2.0
Via: SIP/2.0/UDP 83.167.107.46:0;branch=z9hG4bK47cfc028
Max-Forwards: 70
From: <sip:12345678@sip.asterisk.xxx.com>;tag=as5f389822
To: <sip:12345678@sip.asterisk.xxx.com>
Call-ID: 099f43ef434287c457a3d793535e9df7@yyy.ru
CSeq: 3084 REGISTER
User-Agent: SweetHome Agent
Expires: 120

My solution:
diff chan_sip.c.bak chan_sip.c
2628c2628
<               p->socket.port = htons(r->portno);
---
>               // p->socket.port = htons(r->portno);

When transmitting a register set the socket port to the local one for the transport being used, not the port for the remote server.
