unable to reINVITE call when call is ringing
Hi all,
I'm stuck on updating the call when there is a network change and when the call is 180 RINGING.
This is what's happening:
19 18:39:17.969198 4.944294 iPhone Server SIP/SDP 1121 Request: INVITE sip:225@sipproxy.voipgrid.nl |
22 18:39:17.969839 4.944935 Server iPhone SIP 424 Status: 100 Trying |
25 18:39:17.970483 4.945579 Server iPhone SIP 595 Status: 407 Proxy Authentication Required |
27 18:39:17.970755 4.945851 iPhone Server SIP 500 Request: ACK sip:225@sipproxy.voipgrid.nl |
29 18:39:17.971140 4.946236 iPhone Server SIP/SDP 1331 Request: INVITE sip:225@sipproxy.voipgrid.nl |
33 18:39:18.989949 5.965045 Server iPhone SIP 868 Status: 180 Ringing |
Now I force a network change, which will trigger a unregister and register
57 18:39:24.863085 11.838181 iPhone Server SIP 701 Request: REGISTER sip:sipproxy.voipgrid.nl;transport=tcp (remove 1 binding) |
59 18:39:24.864190 11.839286 Server iPhone SIP 587 Status: 401 Unauthorized |
61 18:39:24.867623 11.842719 iPhone Server SIP 915 Request: REGISTER sip:sipproxy.voipgrid.nl;transport=tcp (remove 1 binding) |
62 18:39:24.868169 11.843265 Server iPhone SIP 473 Status: 200 OK (0 bindings) |
64 18:39:24.869229 11.844325 iPhone Server SIP 801 Request: REGISTER sip:sipproxy.voipgrid.nl;transport=tcp (1 binding) |
65 18:39:24.870765 11.845861 Server iPhone SIP 588 Status: 401 Unauthorized |
67 18:39:24.872639 11.847735 iPhone Server SIP 1017 Request: REGISTER sip:sipproxy.voipgrid.nl;transport=tcp (1 binding) |
68 18:39:24.873235 11.848331 Server iPhone SIP 601 Status: 200 OK (1 binding) |
At this stage I want to reinvite the call:
pjsua_call_reinvite((pjsua_call_id)self.callId, PJSUA_CALL_UPDATE_CONTACT, NULL);
This is my log output:
pjsua_call.c .....Unable to reinvite because another media operation is in progress
I can find in the source why this isn't happening, this was added in this changeset:
https://trac.pjsip.org/repos/changeset/4750/pjproject https://trac.pjsip.org/repos/changeset/4750/pjproject
So my provisional media count is bigger than my media count. Quick look at the call info, this is what I found in the call_info:
media_cnt = 0
prov_media_cnt = 1
The prov_media array has at the first index a type PJMEDIA_TYPE_AUDIO that is not in de media_cnt.
I'm not aware that I activated something somewhere in the process. Could someone explain where this difference is coming from?
Greets,
Bob
