Hi, In "pjsua_acc_config.transport_id", they said that "account should be able to send requests using any available transports according to the destination" "transport will be selected automatically based on the destination of requests upon resolver completion" How is this achieved? I can't find which code shows the transport selection based on destination Please help -- Khoa Pham HCMC University of Science Faculty of Information Technology -------------- next part -------------- An HTML attachment was scrubbed...
