Hi I'm sending custom SIP INFO message from my PBX to my PJSIP client. I'm able to hook on the reception of the SIP INFO message with the on_call_tsx_state pjsua callback. I an see my custom data embedded in in the msg_bug, the whole INFO message. However, I'm wondering as best practice what is the correct way, using the various PJSIP parsing and pj_str functions, to extract my custom data from the SIP INFO message. How should I extact "Custom_INFO_message: some_data" data whithin the SIP message body ? J.G.

Hello A simple solution would be to copy the information in rdata into a null terminated string and deal with it like so: // allocate memory for our null terminated string for the length of the received data + 1 char *body = malloc(rdata->msg_info.msg->body->len + 1); // zero the allocated memory memset(body, 0, rdata->msg_info.msg->body->len + 1); // copy over from rdata into body. the last byte of body will be zero. memcpy(body, rdata->msg_info.msg->body->data, rdata->msg_info.msg->body->len); // the SIP INFO data is now a string in `body` // ... do stuff with it // make sure you free the memory afterwards free(body); On Wed, Apr 5, 2017 at 12:19 PM, John Gathm <john.gathm@gmail.com> wrote: > Hi > I'm sending custom SIP INFO message from my PBX to my PJSIP client. > > I'm able to hook on the reception of the SIP INFO message with the > on_call_tsx_state pjsua callback. > > I an see my custom data embedded in in the msg_bug, the whole INFO message. > > However, I'm wondering as best practice what is the correct way, using the > various PJSIP parsing and pj_str functions, to extract my custom data from > the SIP INFO message. > > How should I extact "Custom_INFO_message: some_data" data whithin the SIP > message body ? > > J.G. > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip@lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org >
