Hello I use a cisco 2600 as sip gw, and i have an error when i make call forwarding, the caller do not receive the ringing tonne. example: the GW receive a call from the pstn (caller1), and he forward this call to the proxy. on the proxy a call forwarding is activated to a mobile phone, so the proxy rewrite the sip uri, and the call is forwarded to the same GW. the problem is that caller1 never receive the ringing tone. I see that the GW correctly send and receive the 183 Session Progress message but he never send this on the pstn. I have also tried to used 2 different GW but I have the same problem.
