[OpenSIPS-Users] Send 487 request terminbated while a cancel recieved from UAC

[M.Khaled W Chehab]

Dear Bogdan ,

 

I am not trying to do something against RFC, but I have a problem you can
see it clear  in the attached capture file,

On wire shark time line (30.877027)  the Client with IP ( 74.114.101.170)
sends  a cancel ,and the opensips version 1.8.2  server with IP
89.207.133.144   send the client 200 canceling and  in its terms forward the
cancel to the trunk provider with IP 74.114.101.190 ,but at wire shark
31.015333 time line you can see  that the trunk sends a 200 OK  ,then 487
request terminated  and the billing stops from the trunk provider   .

The problem is opensips didn't hang-up the call and go for the mediaproxy
timeout   stream_timeout = 40.

-how to let opensips cancel the call immediately  and stop it with no
billing .

 

 

Regards

Khaled

Hi Khaled,

That is a bit against RFC - a proxy must not process the CANCEL (like
terminating the INVITE), but to send it to the callee party and let the
callee decide if the call should be canceled or not. So what you try to do
is against RFC.

Dears ,

 

How to send a  487 request terminated   and drop the call directly  if the
UA send a cancel ,since now I am sending 200  canceling to UA and send a
cancel for the Trunk and wait for his  reply  .
