CCM Call Disconnect Issue

Hi,

We are currently facing an issue with Callers disconnecting from the PSTN and callstate on the IP Phone shows active. The call flow is as below

PSTN-->Cisco 3845--->CUCM 5.1

Signalling between the Voice GW & CUCM is SIP and the configs seem fine. Whenever the caller disconnects we recv Q931 disconnect with cause value 31 (Normal Unspecified) and Sip bye with Q850 reason = 31 sent to the callmanager and CUCM responds back with a 200 ok. On the IP Phone the call stays active for 30 secs and then disconnects.

CUCM ver 5.1.2.3000-2

IOS 12.4 15 T9 on Cisco 3845 platform.

Any idea what could be causing the problem?

Thanks
