currently iI have a SIP application developed by using PJSIP SIP stack for window Mobile 5.0.
As I try to register to asterisk, it failed. I have check the network traffic, i found that 200 OK cannot receive by the SIP application?
Yet, when i try register with OPENSER SIP server, it successfully registered.
Does anyone know how to solve it?
Any difference between Asterisk , OPENSER SIP server?
Can Asterisk integrate with OPENSER SIP SERVER?
