CME 4.0: Call forwarding when busy for fax machine on FXS?

Hello,

I have got a Cisco 2821 ISR running 12.4(9)T with CME 4.0 on top of that. The router has one VIC-2BRI-NT/TE and one VIC-2FXS as interfaces.

The BRI ports are connected to the PSTN. To the FXS ports fax machines are connected. Several 7940 ip phones connect via LAN.

Basic telephony functions are working just fine, I can place calls and receive calls externally and internally.

We want to configure that if the fax machine on one FXS port is busy, the call is forwarded to the other fax on the other FXS port. My problem is that I can not configure "call forwarding when busy" on the FXS ports. The FXS ports do not show up in the GUI since they are no ephones.

I have tried huntgroups, but only ephones are allowed as huntgroup members and the fax machines are no ephones.

Is there a way to configure call forwarding for the FXS ports on my CME?

Thanks for your help!

Best regards,

Eyad.

Hi Eyad!

I understand your problme.

I think to solve your issue you have to use some trick!

assign to yor fax a two number that do not overlap with phone dial plan(for example phone 2xx and fax 3xx)

dial-peer voice 1 pots

destination-pattern 301

port 0/2/0

!

dial-peer voice 2 pots

destination-pattern 302

port 0/2/1

dial-peer voice 3 pots

preference 1

destination-pattern 30.

port 0/2/0

!

dial-peer voice 4 pots

preference 2

destination-pattern 30.

port 0/2/1

if users want to send a fax to 301 the call will match dialpeer 1,3,4 and if the fax is busy the call will be send to voice port 0/2/1

Maybe this conf could work out,you have to try
