Call to Premium rate number fails after 3 rings

Have a cucm 7 installation with H323 gateway to PSTN

Trying to call a premium rate number and the call fails / disconnects after 3 rings.

Have ran debug isdn q931 and debug voice ccapi and they indicate call is being passed to PSTN via correct dial-peer etc... but they only indicate "normal call clearing" when call is diconnected...

DNA shows hitting right route plan too

If you call number from a mobile it rings once and connects to IVR...

have passed this onto telco but they advise there is no error on there part.

Does anyone know if this could be a cucm issue, or if there is a way to 100% confirm its not?

Re: Call to Premium rate number fails after 3 rings

Check who sent disconnect in debug isdn q931 output. If it is received from the telco ask them why, probably you set incorrect type/plan or ANI. If it is sent from gateway check the sh call hist vo id $id for internal error code and release source. If you find that disconnect sent by UCM check the traces in RTMT.
