Hello list,
I have several questions about the support of TCP in OpenSER in
general, and about the switch/ failover from UDP to TCP in particular.
Forcing UDP->TCP failover will only work if the client is listening on
TCP too - and the proxy knows the port where the client is listening.
If the client has registered using UDP, then the proxy has to use UDP
for sending requests to this client.
Thus, if you want TCP you have to make sure that the clients use TCP and
openser will automatically use TCP.
you can force some clients to use TCP by adding NAPTR records for you
domain with TCP as the preferred protocol.

In my setup, I have several SIP clients registered to a single
OpenSER, and they exchange presence messages on a peer-to-peer basis.
When the presence document is complex, the size of the message sent
exceeds a given limit, and I want my message to be sent over TCP. My
clients are registered on the OpenSER, and the REGISTER has been sent
over UDP. From now, when client A sends a NOTIFY using TCP to client
B, the message is transported over TCP from A to the OpenSER, and is
transported over UDP from the OpenSER to B.
So here are my questions :
- How can I tell OpenSER to relay the message to B using TCP ?
- Do I have something particular to do while registering to tell
OpenSER that the client is listening in UDP and TCP ?
Thank you in advance for your answers,
Antoine
