[reSIProcate-users] Forcing an Outbound Transport-Type

[Gabriel Hege <gabriel-mailinglists@xxxxxx>]

Hi,

What is the proper way to force a transport type (e.g. TCP) for an 
outgoing request - or even better for all request from a certain 
UserProfile?

The comments in Profile.hxx suggest that somebody thought about using 
setOverrideHostAndPort() to also populate the Via entries, but it is not 
implemented.

I tried setting the transport for the first Via of a request like this:

 invite_msg = mp_dum->makeInviteSession( m_to_addr, m_profile, &m_sdp, 
new MyAppDialogSet(*mp_dum) );
 invite_msg->header(h_Vias).front().transport() = "TCP";
 mp_dum->send(invite_msg);   

        

but the message is still sent over the wire as UDP, although it contains 
the following header:

 Via: SIP/2.0/TCP 
141.22.27.150:5060;branch=z9hG4bK-d8754z-bf3a78252072422c-1---d8754z-;rport



findTransportByVia() and findTransportBySource() are actually called in 
the TransportSelector, since I do have setFixedTransportInterface() set 
for the used profile.

Can anybody give me some advice please?

Thank you,
