I have a setup like this,
CUCM7.5 --- CUBE ----OmniPCX4400
Cube is acting as H323 gateway and PSTN gateway.
The problem is the call from OmniPCX to CUCM7.5 which is set to CFA to PSTN number drops after one ring.
(All other stuff works fine, such as call transfer).
Below is the related configuration.

Can you please post the PRI-interface configs. Are you able to dial from OmniPCX to PSTN via H323 GW?
Good question. OmniPCX has its own PRI trunk to PSTN. The H323 gateway is used between internal phones(from OmniPCX phones to CUCM phones) and to provide PSTN connection to CUCM phones.
The design is not so fancy(this was implemented long time ago, i don't know when...), but I'd like to know if the call forward is possible in this design.
controller E1 0/0/1
pri-group timeslots 1-31
no ip address
no logging event link-status
isdn switch-type primary-net5
isdn incoming-voice voice
isdn map address .* plan national type unknown
isdn bchan-number-order ascending
no cdp enable
One more thing, when the call was forwarded to PSTN and dropped, the q931 shows normal call clearing.
Can you try adding this to the config:-
Thanks for your input.
But that didn't make any difference.
From the isdn debugs, do you see the router forwarding all the digits to telco? Please post the q931 debugs as well.
