Hi, I'm using pjsip-ua Client Registration API to send register request. As I understand, PJSIP will send request to url specified by srv_url in pjsip_regc_init. This srv_url will then appears in the request header. I would like to specify a SIP Domain name different than server machine url. I tried to use the route header, initializing srv_url with domain name and adding the actual machine url in route_set, obviously without any success. Is there any way to send a request to a specific Domain using the Client Registration API or do I need to use the low-level API to achieve it. Thanks.
