Hi, I have SIP (D-Link DPH-C160s) phone running off a v4 SES server on ACM 3.1.4 set up mas OPS.
When the SIP phone calls another station and hangs up during the ringing phase, the SIP phone sends a CANCEL message as expected.
This message appears to be ignored, and the ACM continues with Ringing messages.
Eventually it receives a 408 request timeout, and clears the destination party down.
Any reason why the CANCEL would be ignored?. Have heard it can be ignored if it recives a 200 OK message at the same time (eg actually answered and then expects a BYE message), but nothing like that here.
Otherwise all seems to work OK.
