Hi All, I am using pjsua_call_make_call API for sending INVITE from my application. By default the From header contains the URI specified in the id parameter Of pjsua_acc_config structure. But I want to have different CLI (From header) for different calls. So I tried to change this id before calling pjsua_call_make_call And added following code for this: Char* strFrom = "sip:5555@10.0.0.1"; g_acc_cfg.id = pj_strdup3 (pool, strFrom); status = pjsua_acc_modify(g_acc_id, &g_acc_cfg); status = pjsua_call_make_call (g_acc_id, &uri, 0,0, &msg_data, &call_id); In my case pjsua_acc_modify is working fine. But pjsua_call_make_call fails and returns status code 171039. This status code is returned when there is something Wrong with the URI. But in this case I don't see any thing wrong with the URI. Please suggest what is going wrong. Thanks, Jitendra -------------- next part -------------- An HTML attachment was scrubbed...
