[Serusers] Problems with CANCEL on Xlite

Hello,

 

I am using the X-Lite 2.0 build 1086 with ser 0.8.11 and noticed a strange behaviour regarding the CANCEL method. Whenever the X-lite sends a CANCEL to a Cisco gateway after having received a 183 Session Progress, the gateway sends back a 481 Call Leg/Transaction Does Not Exist. This way, the call is not being canceled as the called phone will keep ringing. If no 183 Session Progress is received, the call is normally canceled.

 

Any ideas on this issue? Has anyone has experienced the same problems?

 

Thanks,

Chuck Ramirez
