DID DTMF Assistance Please?

[GeorgeKC]

All - I'm having a bit of trouble understanding whether our current fax setup will allow DNIS digits to be passed from the PSTN to our fax server modems as DTMF.


--Two PRI's from PSTN terminate on separate VWIC-1MFT-T1 cards in a Cisco 2651XM router which is also our h.323 gateway.
--CallManager running v4.3
--Fax server has voice modems connected to Cisco VG248 ports.


I thought the VG248 could produce the DTMF digits after the modem answers but, if it can, I'm obviously unclear where or how this can be configured.

Could someone enlighten me or tell me if I'm wasting my time trying to do this?


Thanks,
Greg

You will need a device that does h323 to pass DTMF after connecting like a VIC2-4FXS/DID module that will go into a router. I do not believe you can do it with MGCP devices which is what a VG248 is.
