Hi Curt, Yes, you'll need 30 accs for 30 calls, it is the simpler way. Another way should be manually inserting route header into INVITE message in tx_data (which you mentioned to be not working, well, it should), e.g: -- pjsua_msg_data msg_data; pjsip_route_hdr *h; pjsip_sip_uri *url; url = pjsip_sip_uri_create(pool, 1); pj_strdup2(pool, &url->host, "1.2.3.4"); url->lr_param = 0; h = pjsip_route_hdr_create(pool); h->name_addr.uri = (pjsip_uri*)url; pjsua_msg_data_init(&msg_data); pj_list_push_front(&msg_data->hdr_list, h); pjsua_call_make_call(..., &msg_data, ...) --- Note that the route/proxy setting alone doesn't seem to solve the certificate verification problem (see my first reply). You can trick the TLS transport to verify subjectaltname in remote cert against custom defined target name (as it is resolved using non-DNS mechanism) by modifying destination name info in tx_data, e.g: -- pj_strset2(&tx_data->dest_info.name, "p.com"); -- unfortunately, you'll need to modify pjsua_call_make_call() for this!
