iOS doesn’t allow file access. You need to use iOS API to query DNS server IP
which isn’t done for Sofia SIP yet.

Subject: [Sofia-sip-devel] Sending nua_invite - DNS Error 503
Hey,
I got good help from that mailing list last time. So I’ll try again to send my
problems to you.
When I’m sending a nua_invite message I get a DNS 503 error.
I saw some mails in the archive concerning this problem, but I could not find a
good answer for that problem.
I am working with an iPhone and the newest version of sofia sip.
The confusing is, that it worked two days ago and now it doesn’t.
I didn’t changed anything in the code.
Here’s my code:
app.nua = nua_create(app.root,
event_callback,
NULL,
NUTAG_URL("sip:0.0.0.0:5060"),
TAG_END());
su_root_run (app.root);
//Invite
url_string_t *url = URL_STRING_MAKE("sip:mu...@iptel.org:5060") ;
sip_to_t *to = sip_to_create(NULL, url);
op.handle = nua_handle(app.nua, NULL,SIPTAG_TO(to), TAG_END());
nua_invite(op.handle,SOATAG_USER_SDP_STR("m=audio 5004 RTP/AVP 0 8"),
TAG_END());
Here’s my output:

The problem is that sofia sip tries to call to 127.0.1. which is obviously not
the IP of iptel.org<http://iptel.org>.
I hope some of you have a good answer for me.
Thank you very much !
