Sounds like:
CSCtc48579    Inbound H323 call to UCM 7.1.3 gets silence forcaller and
then drops

Hi,

Since the upgrade to CUCM 7.1.3 we face a problem with incoming calls
from our H323 Gateways, which are connected to the PSTN via E1 PRI. It
seems that only calls from ISDN lines come through. Calls from analog
Lines get disconnected after some time. 

Before the CUCM upgrade all calls worked fine. Does anybody knows about
an BUG with CUCM 7.1.3 and H323?

During my troubleshooting I found the following error  in the CCM
Traces, for a call from an analog PSTN Line:
