Hi all,

I have been asked to add a fax machine to a cisco VOIP network UC540 switch. I have access to the config assistant. the site has a number of phone numbers associated to the voip.

I am a little confused by how I specify a particular number to go to the fax machine on FXS port 1 and not ring the desk phones

any help would be appreciated.

Many thanks

To do this is fairly easy... from within the configuration assistant do the following:

Configure > Telephony > Users & Phones
Select the Analog Extensions tab and give the FXS port an extension number (like 301).

The next part depends on if your incoming lines are on a trunk or via the FXO ports... here is both scenarios...

If incoming lines are FXO ports:
Configure > Telephony > Dial Plan > Incoming
From the Incoming FXO calls tab, for the FXO line that the call is coming in on, enter the destination as the extension number you configured above (301).

If incoming lines are trunks:
Configure > Telephony > Dial Plan > Incoming
From the Direct Dialing tab, Click add, select the incoming trunk and then enter the phone number you want forwarded to the fax machine (like 5551234) in the PSTN Numbers section under both the DID start and end number fields. Then for the Internal Extensions section put in the extension number (like 301) in the Start and End numbers part.

Great discription of the options, but if the line was coming in over FXO, I would not waste the FXO port on the UC and would simply connect the line directly to the fax.
