Hi:
??? I am using pjsip v1.4 to implement my application, and I want my app using tcp connect to SIP server.
??? The pjsip is using a random socket port( In via header, e.g. 2050) to register to sip server.
?? ?But, in the Contact header, the specific port we want is 5060.
?? ?I want the port in the Via and Contact is the same value (5060).
?? ?How can I do to reach the goal?
?? ?
??? My step is as below:? ?
??? First, in system init, it already created the default tcp transport. (partial code as below)
??? |-------------------------------------------------------------------------|
?? ? pjsua_transport_config cfg;????????????????????????????????????????????? ?
?? ?????????????????????????????????????????????????????????????????????????? ?
???? /* config the first transport port.*/??????????????????????????????????? ?
?? ? pjsua_transport_config_default(&cfg);??????????????????????????????????? ?
????????????????????????????????????????????????????????????????????????????? ?
?? ? status = pjsua_transport_create(PJSIP_TRANSPORT_TCP, &cfg, NULL);??????? ?
?? ? if (status != PJ_SUCCESS)??????????????????????????????????????????????? ?
?? ????? error_exit("Error creating transport TCP", status);????????????????? ?
?? ?|-------------------------------------------------------------------------|
?? ?
?? ?Then, I add a account (ex:7219) to registe to SIP server, and capture the register packet. (as below)
?? ?|----------------------------------------------------------------------------------------------|
?? ? REGISTER sip:192.168.1.10 SIP/2.0??????????????????????????????????????????????????????????? ?
???? Via: SIP/2.0/TCP 192.168.1.8:2050;rport;branch=z9hG4bKPjfe940641-ca72-464f-b6aa-5bb48ce7c896 ?
