It is only about the returned value of the variable $dp. The port is not set in the outbound proxy uri. The logic is, if the $du has no port value, then return 5060 -- probably some old code relying on default value for port -- relevant piece of code inside the pv module: ``` } else if(param->pvn.u.isname.name.n==2) /* port */ { if(uri.port.s==NULL) return pv_get_5060(msg, param, res); return pv_get_strintval(msg, param, res, &uri.port, (int)uri.port_no); ``` --- You are receiving this because you are subscribed to this thread.
