Hello,
I'm having a problem when using the Replaces header in a INVITE.
It seems if the party replies with "407 Proxy Authentication Required" and nua_authenticate is called, nua does not send the new INVITE with authentication data at all. Then, some 20 seconds after that, we receive nua_r_invite with Status=503 Service Unavailable (not received from the network, but generated by the stack itself). To generate the scenario above, I'm simply adding the Replaces header (I've tried first with SIPTAG_REPLACES_STR, and then I tried with SIPTAG_REPLACES with the same result) in a nua_handle/nua_invite piece of code known to be working.
Am I missing something?
Sorry, my mistake.
Sofia is indeed trying to send the message.
It turned out, the INVITE containing the additional authentication data was too large:
/INVITE (95600833) too large for UDP, trying TCP/
so it was trying to open a TCP connection to the server that has no TCP port enabled.
