Registration failed in Asterisk

Hi all,

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?



Asterisk and Ser are different things, Asterisk is a sip b2bua ( and Ser is sip proxy/registrar/redirect server.
And yes, Asterisk can be integrated with Ser, Asterisk can use it as its sip proxy.
