VoiceGW: Selective forwarding on incoming fax

Hello!

I would like to obtain this feature on a VoiceGW: to forward an incoming fax to a certain fax machine (different from the called fax machine) if the calling fax machine has a specified phone number.

For example: if fax A sends a fax to B, the document is actually received by fax C. If the calling fax is not A, the document is received by B.

I have a range of 100 numbers for the fax machines (on a fax server): ABCDEF6XY (i.e., ABCDEF600 to ABDEF699).

The dial-peers matched when a fax arrives are the following:

dial-peer voice 30 pots

incoming called-number ABCDEF...

direct-inward-dial

!

dial-peer voice ABCDEF600 voip

description INCOMING FAX FROM PSTN TO STONEFAX ABCDEF6..

huntstop

destination-pattern ABCDEF6..

voice-class h323 1

session target ipv4:GHI.JKL.MNO.PQR:1721

dtmf-relay h245-alphanumeric

codec g711alaw

fax rate 14400

fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback cisco

ip qos dscp cs5 media

ip qos dscp cs5 signaling

no vad

!

I suppose I have to use some voice translation rules and some new dial-peers, but I don't know how.

Anyone can help me?

Thanks in advance!

Re: VoiceGW: Selective forwarding on incoming fax

Ensure that the fax mode matches between the gateways. In particular, if you leave the CallRestartTimer with the default setting of 5000 ms, the 6624 port uses fax pass-through. To use fax relay, change this value to 1235. The other option is to use fax pass-through on the H323 gateway.

For the Cisco CallManager configuration, perform these steps:

Open up the Cisco CallManager Administration panel.

Click the 24 port Foreign Exchange Station (FXS) blade configured on your Cisco CallManager.

Select the port you are using (port to which your fax has been connected).

Set the CallRestartTimer to 1235 ms. Click Update.

Note: This procedure only applies to skinny gateways, not to H.323 gateways.

If you leave the CallRestartTimer with the default setting of 5000 ms, the port uses fax pass-through. If that is the case, make sure to also use fax pass-through on the H.323 gateway.

To configure the H.323 gateway fax relay, set the fax-rate command to 9600 or 14400 baud in cases where the default G.729 codec is being used, as shown. When using G.711, this command is not required.

dial-peer voice 2 voip

destination-pattern 2000

session target ipv4:10.200.72.37

fax-relay ecm disable

fax-rate 9600!

dial-peer voice 3 pots

destination-pattern 0T

direct-inward-dial

port 1/0:15To configure the H.323 gateway for fax pass-through, issue the fax rate disable command on the voip dial peer, as shown:
