Good evening dear developers,
I’m currently stuck in another problem.
I am able to retrieve incoming calls. So my nua_create should be right.
In my nua_invite I’m trying to connect to an IP Address directly. I am using
IP4, but the computer which I try to call does run IP6, too.
When I try to connect sofia sip is not able to find out the way to my computer
and I get a timeout in the end.
I am still using an iOS Device for testing, so I am not able to use the DNS
resolver.
Is it possible to deactivate the resolver directly in my code ?
Here’s my invite:
url_string_t *url = URL_STRING_MAKE(“sip:alex@192.168.178.82:5060") ;
sip_to_t *to = sip_to_create(NULL, url);
op.handle = nua_handle(app.nua, NULL,SIPTAG_TO(to), TAG_END());
// op.leg = nta_leg_tcreate(app.agent,nta_callback, NULL, SIPTAG_TO(to),
TAG_END());
nua_invite(op.handle,SOATAG_USER_SDP_STR("m=audio 20000 RTP/AVP 0\n"
"a=rtpmap:0 PCMU/8000\n"
"v = 0\n"
"o=Alex\n"
"c=IN IP4 127.0.0.1\n"
"s=Audio"),
TAG_END());
Here’s my Log Output:

I think I just have to disable the DNS resolver.
I hope you have some good ideas.
By the way. This is a very good mailing list.
