Hi All,

Can someone checks why, in the situation of a client that cancels a call before the destination send a “180 ringing” to the proxy, that causes some troble to the proxy because it is not forwarding the cancel to the destination.

See the following 2 examples :

In this situation the cancel works fine:

651.327850 10.112.128.220 -> 10.112.128.247 SIP/SDP Request: INVITE sip:testef03@teste.pt, with session description

651.328725 10.112.128.247 -> 10.112.128.220 SIP Status: 100 trying -- your call is important to us

651.328778 10.112.128.247 -> 10.112.128.187 SIP/SDP Request: INVITE sip:testef03@10.112.128.187:7678, with session description

651.723084 10.112.128.247 -> 10.112.128.220 SIP Status: 200 cancelling

651.899824 10.112.128.187 -> 10.112.128.247 SIP Status: 200 OK

In this one, the cancel never reaches the destination client, so it keeps ringing…
