Pre Sales help specifications for 2821

Question asked by on Mar 9, 2010

I am needing to specify the required components for a fax project I am working on.  A brief description of the project is:  One T1/PRI from the PSTN connecting to a Cisco 2821 ISR. This will cross connect using DI to the PBX.  I have spec'd the vwic2-2mft-t1/e1 2 port multiflex trunk voice/wan card to accomplish this.

I have also spec'd the PVDM2-16 for call processing and IP Voice IOS and 256MB CF upgrade.


I will be terminating 8 channels from the PRI on the router for T.38 fax processing to our FOIP server.  The remaining PRI channels will be cross connected to the PBX (as mentioned above).  Our certified cisco distributor indicates this is all I need.  In reading as many cisco docs as possible it is still not clear to me whether or not I need a Network Module such as the NM-HD-2VE to deal with the TDM to packet data.


So my question is do I need the NM to accomplish my object of converting the incoming PRI fax calls to packet data and T.38 to my FOIP server?


Thanks in advance!
