FAQ:

Hi all! Due to the difficulities to support ISDN Data with Cisco gateways ... Are there any experiences in connecting an IPXXX BRI Gateway via H.323 to the Cisco Call Manager? Does this work? Are there helpful configuration hints?

Answer:

This has been done before successfully. The GW must be configured as H.323 gateway in the CM. The latest info we have is that CM does not support overlapped sending though, so in the inno GW, calls must be translated to block dial (using timeout or fixed number length).
