FAX config on 2811??

I have a 2811 VGW registered to CUCM 7.02, is it an H.323 gateway.  Local PSTN is coming in on a PRI circuit connected to the VIC-2TMFT-T1/E1.  One of the inbound numbers on that PRI is a fax number (5551236789) that I need to port out of the FXS card (voice-port 0/2/0) to the fax machine.  Also need to allow for outbound fax sending.

Would someone mind posting sample config that will help me understand and accomplish this?  I find plenty of examples, but don't completely understand what is pertinent for creating both inbound/outbound config.

Re: FAX config on 2811??

First, your incoming dial peer should cover all incoming calls on the PRI and include the direct-inward-dial command. This will cover you for the inbound call leg. The outbound dial peer could look something like this:

dial-peer voice 21 pots

description Fax

destination-pattern 5551236789 <-- This assumes that the provider is sending you 10 digits on the PRI.

incoming called-number . <-- This is used to match this as an incoming dial peer for outbound faxes.

voice-port 0/2/0

codec g711ulaw  <-- used for passthrough

fax rate voice <-- used for passthrough

fax protocol t38  ls-redundancy 0 hs-redundancy 0 fallback cisco <--used for fax relay

You do not need both the passthrough or relay commands. I would recommend just using the relay command.

You don't need any fax commands for that.

Just configure the DP with the right numbers, and that's all.
