Another related problem, the "Require: 100rel" will only be included in the
180 Ringing if SIPTAG_REQUIRE_STR("100rel") is included in the nua_respond
parameter list. Calling nua_set_hparams() with SIPTAG_REQUIRE_STR("100rel")
doesn't do the trick.

Pekka,
I commented out the entire if-statement below, and now I see the 180 Ringing
get transmitted with the "Require: 100rel" header.
Are there any side-effects/pitfalls to doing this?
Best Regards,
Jerry

I think this is a bug, because RFC 3262 says a provisional response can
contain a "Require: 100rel", even if the request original request only
indicates "Supported: 100rel").
However, in the function nua_invite_server_respond(), the following
if-statement causes the function to exit with return value of 0 or -1
(because reliable=1 and sr->sr_status=180), and nua_base_server_respond()
does not get called.
if (reliable && sr->sr_status < 200) {
...
if (...) {
return -1;
}
...
return 0;
}
Any suggestions on how to fix this?
Best Regards,
Jerry

Does your client indicate that it supports 100rel? If not, then Sofia eats
your 180.
