invite not going in ios

I am trying to call a contact via pjsip in my ios application but the
INVITE message itself is not going. But strange thing is if I call the
registered account in PJSIP from another third party app such as linphone I
am able to do proper video call. I am using Kamailio as my SIP server,
there I have LOG for every INVITE message. When I am calling from pjsip it
is not showing up in the logs whereas the other apps' INVITE messages are
showing up which means the INVITE call itself is not going to the server.

The code I am using is below:

char *uriString = "sip:901@103.135.128.121:7879";

pj_str_t uri = pj_str(uriString);

AppDelegate *appDelegate = (AppDelegate *) [[UIApplication

sharedApplication] delegate];

pjsua_call_id p_call_id;

pjsua_call_setting opt;



pjsua_call_setting_default(&opt);



opt.vid_cnt = 1;

opt.aud_cnt = 1;



pjsua_msg_data msg_data;

pjsua_msg_data_init(&msg_data);



pj_status_t status = pjsua_call_make_call(appDelegate.accountId , &uri,

0, NULL, &msg_data, &p_call_id);

*if*(status == PJ_SUCCESS){

    NSLog(@"call made successfully from %d with callID %d",appDelegate.

accountId,p_call_id);

    *if*(pjsua_call_is_active(p_call_id)) {

        NSLog(@"call is active");

    }

}*else* {

    NSLog(@"call made failed");

}

Its giving me PJ_SUCCESS as you can see from the code. Both the success
check is passing though the call is not actually being made.

The logs I am getting in XCode is like below:

I am trying to call a contact via pjsip in my ios application but the INVITE message itself is not going. But strange thing is if I call the registered account in PJSIP from another third party app such as linphone I am able to do proper video call. I am using Kamailio as my SIP server, there I have LOG for every INVITE message. When I am calling from pjsip it is not showing up in the logs whereas the other apps' INVITE messages are showing up which means the INVITE call itself is not going to the server. The code I am using is below: *char* *uriString = "sip:901@103.135.128.121:7879"; pj_str_t uri = pj_str(uriString); AppDelegate *appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate]; pjsua_call_id p_call_id; pjsua_call_setting opt; pjsua_call_setting_default(&opt); opt.vid_cnt = 1; opt.aud_cnt = 1; pjsua_msg_data msg_data; pjsua_msg_data_init(&msg_data); pj_status_t status = pjsua_call_make_call(appDelegate.accountId , &uri, 0, *NULL*, &msg_data, &p_call_id); *if*(status == PJ_SUCCESS){ NSLog(@"call made successfully from %d with callID %d",appDelegate. accountId,p_call_id); *if*(pjsua_call_is_active(p_call_id)) { NSLog(@"call is active"); } }*else* { NSLog(@"call made failed"); } Its giving me PJ_SUCCESS as you can see from the code. Both the success check is passing though the call is not actually being made. The logs I am getting in XCode is like below: 11:43:02.678 pjsua_call.c !Making call with acc #0 to sip:901@ <MY_IP>:<MY_PORT> 11:43:02.678 pjsua_aud.c .Set sound device: capture=-1, playback=-2 11:43:02.678 pjsua_aud.c ..Opening sound device (speaker + mic) PCM@16000/1/20ms 11:43:02.678 coreaudio_dev.c ...Using VoiceProcessingIO audio unit 11:43:03.182 coreaudio_dev.c ...core audio stream started 11:43:03.191 pjsua_media.c .Call 1: initializing media.. 11:43:03.192 pjsua_media.c ..RTP socket reachable at 192.168.1.185:4004 11:43:03.192 pjsua_media.c ..RTCP socket reachable at 192.168.1.185:4005 11:43:03.192 pjsua_media.c ..RTP socket reachable at 192.168.1.185:4006 11:43:03.192 pjsua_media.c ..RTCP socket reachable at 192.168.1.185:4007 11:43:03.193 pjsua_media.c ..Media index 0 selected for audio call 1 11:43:03.193 tsx0x102061ca8 ....Temporary failure in sending Request msg INVITE/cseq=12090 (tdta0x102022ca8), will try next server: Unsupported transport (PJSIP_EUNSUPTRANSPORT) 11:43:03.193 pjsua_core.c ....TX 1350 bytes Request msg INVITE/cseq=12090 (tdta0x102022ca8) to UDP <MY_IP>:<MY_PORT>: INVITE sip:901@<MY_IP>:<MY_PORT> SIP/2.0 Via: SIP/2.0/UDP 103.78.19.70 :<MY_PORT>;rport;branch=z9hG4bKPjlK38zIfNAOehpCfRHKJsAhPsYYBgcZwm Max-Forwards: 70 From: sip:1001@<MY_IP>;tag=ll1r5bccrs7o9.Y24PntSkfvusfNGjSa To: sip:901@<MY_IP> Contact: <sip:1001@103.78.19.70:<MY_PORT>;ob> Call-ID: UO0bmgkIaqC-svFw1ZmsULsGqnwP9qke CSeq: 12090 INVITE Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, INFO, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS Supported: replaces, 100rel, timer, norefersub Session-Expires: 1800 Min-SE: 90 User-Agent: AnuranRealSIPObj Content-Type: application/sdp Content-Length: 726 v=0 o=- 3771123183 3771123183 IN IP4 192.168.1.185 s=pjmedia b=AS:386 t=0 0 a=X-nat:0 m=audio 4004 RTP/AVP 98 97 99 104 3 0 8 9 120 96 c=IN IP4 192.168.1.185 b=TIAS:96000 a=rtcp:4005 IN IP4 192.168.1.185 a=sendrecv a=rtpmap:98 speex/16000 a=rtpmap:97 speex/8000 a=rtpmap:99 speex/32000 a=rtpmap:104 iLBC/8000 a=fmtp:104 mode=30 a=rtpmap:3 GSM/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:9 G722/8000 a=rtpmap:120 opus/48000/2 a=fmtp:120 useinbandfec=1 a=rtpmap:96 telephone-event/8000 a=fmtp:96 0-16 m=video 4006 RTP/AVP 97 c=IN IP4 192.168.1.185 b=TIAS:256000 a=rtcp:4007 IN IP4 192.168.1.185 a=sendrecv a=rtpmap:97 H264/90000 a=fmtp:97 profile-level-id=42e01e;
