*INFO: No all SIP headers in the TCP buffer.

I tried to debug and I found: 

tnet_transport_cfsocket.c line 134

ret = len = CFReadStreamRead(active_socket->cf_read_stream, buffer, 
(CFIndex)TNET_BUFFER_STREAM_MIN_SIZE);

Buffer is truncated to TNET_BUFFER_STREAM_MIN_SIZE(1024) bytes. Therefore 
INVITE is truncated and call is terminated.

It's correct to truncate the message. You can even send it byte by byte :)
The stack will concatenate all message until it gets the complete headers and 
content.
"*INFO: No all SIP headers in the TCP buffer." -> not an error, it's expected 
for any connect transport (TCP, TLS, WebSocket...)

Thanks for answer. I attached log files when TLS is enabled.

I found problem. Our server sends route field with no port and doubango tries 
connect to peer with port 5060 by default. Is it right?
