Route FXS port to dedicated FXO port

Hi,

I have a UC500 with CME7. There are 3 connected FXO ports and 1 FXS port as fax.

The IP phone does not have to dial a prefix for an outside line. The fax should always use the 3rd FXO port.

How can I configure a dial-peer / voice translation so that FXS port 0/0/0 always uses FXO port 0/1/3

without dialing a prefix like 9 or so.

Thx

Filip

Re: Route FXS port to dedicated FXO port

Hi Filip,

You can use cor lists to do this, or you can use translation patterns.

The idea is for the fax machine to dial a normal number, the router will add a prefix for routing, match the appropriate dial peer, and then strip the prefix before sending it out. This is transparent to either end.

It would look something like this:

voice translation-rule 1

rule 1 /\(.*\)/ /9999\1/

voice translation-profile 1

translated called 1

dial-peer voice 1 pots

port 0/0/0

translation-profile incoming 1

dial-peer voice 2 pots

port 0/1/3

destination-pattern 9999.T

What happens:

Call from FXS hits dial peer 1, router adds 9999. Router searches for a dial peer that matches the 9999.* number, finds dial peer 2. On a pots dial peer, any number explicitly matches is stripped, so the number sent out is the original dialed number.

hth,

nick
