Summary:                    Asterisk sends SIP-over-TCP INVITE to wrong port
number
Description: 
The scenario is that a SIP UA registers with Asterisk using TCP transport.
The UA puts its IP address, port number and transport=tcp parameter in the
REGISTER's Conact: header. Asterisk stores these contact parameters
correctly in its registration table. However, when it comes to sending an
INVITE to this UA, Asterisk puts a wrong port number in the destination
port number field of the TCP header. Due to this, the UA never receives the
INVITE. The TCP port number is actually correct in the SIP payload
including the Request-URI and the To: header in the INVITE, but it's not
correct in the TCP header. 

Asterisk log file and wireshark trace are attached.
