Fax Server & ATA

Hi

Fax server is integrated with voice gateway H323. (IOS version c2800nm-adventerprisek9-mz.124-15.T8.bin)

ATA are registered on CUCM version 7.1.3b (firmware ATA030203SCCP051201A.zup)

Both devices are using the some PRI for external faxes.

We are able to send and receive faxes through PSTN (PRI) on both devices.

We can exchange faxes between them via PSTN call only.

Customer wants to send fax between Fax Server & ATA as an internal call.

Is there a way or a workaround to bypass the incompatibility between T38 (Fax Server) and Pass-through (ATA) and be able to exchange faxes as an internal call?

Current sample configuration on h323 gateway for both Fax Server and ATA
