Sorry I cant understand your problem. Describe your scenario. Who calls whom? What should happen after timeout? (timeout= user does not pick up call)

problem with the timeout of a call. The call continues beyond the timeout and when by the PSTN telephone I reject the call appears the following log message:

Warning: sl_send_reply: I won't send a reply for ACK!!

you are executing sl_send_reply for an ACK request. That doesn't make sense.

regards klaus

Where I have mistake? Any idea?

Another thing. I see that I redirect the call directly in the media gateway, (for example a location of a user is a PSTN number) whitout the traslation of IP number, all is ok.
