SIP:FXS keep ringing when ATA186 Cancel call

I setup the following

C3640(FXS)---SIP Proxy----SIPHardPhones(C7960 and ATA186)

C3640 IOS 12.2.13T1(10.10.10.50)

C7960 SIP V4.3.0(10.10.10.31)

ATA186 v2.15(10.10.10.35)

SIP Proxy (10.10.10.66)

Problem encountered

When ATA186 call FXS, the phone ring with no pickup

When AT186 hangup, the FXS phone keep ringng.

I had tried with C7960

When C7960 call FXS, the phone ring with no pickup

When C7960 hangup, FXS stop ringing.

I capture the message for both events

On the ATA-FXS case, the C3640 send 481. See below

Re: SIP:FXS keep ringing when ATA186 Cancel call

I am not sure if you are hitting this bug CSCdv34778. It is worth checking though

Re: SIP:FXS keep ringing when ATA186 Cancel call

This bug is onlly applicable to ua which is using CFNA with CSPS, and the ua send BYE instead of CANCEL when hang-up.

In my case, I am using SER as SIP proxy. The UA (ATA186) is sending CANCEL indeed and received by the the gateway (FXS)

Thanks
