I'm not doing any fax with sipX at my main site, but I do have a customer who uses a Mediant to route fax calls into Exchange 2007 UM.
Personally I like to keep things as simple as humanly possible, so any incoming calls to a DID which is a fax number I would definitely route straight to the fax server. Pros : lightens the load on SipX and if something goes wrong you're debugging traffic between 2 points (Mediant and fax server). If traffic is being routed via SipX you've got an extra debugging step which you really don't need. Cons : fax calls won't be included in traffic reports in SipX. If you're getting resource contention (i.e. all your trunks are busy) then that might pose an issue. I can't recommend any open source fax software, but if you don't mind doing it in a Windows world take a look at NetSatisfaxtion products. They work great with Mediants. I have calls from certain fax machines fail to send correctly to Exchange every single time. NetSatisfaxtion receives these calls correctly.

Not sure what else I needed to say until someone asked some questions I guess :). The fax calls would be coming into the mediant 2K, I need to route them to a fax server. Someone on the list once told me that I could route the fax either from the gateway or from sipx. The comment was in passing as we were talking about something else. I could have misunderstood him, it's just what I seemed to remember. > In my current setup, I use a Patton 4960 with multiple DIDs. Two numbers > are given out as fax numbers.

This is what I am trying to get a handle on because sipx is SIP based but I was sure this person was telling me he would route fax calls using sipx. Now, I don't want to bother using up any sipx resources so if it is better to route from the mediant, that's fine too. Thought I would ask in the list as I'm sure others are doing things along these lines. > I am unfamiliar with the mediant gateways (you didn't specify which one you > have).

It will more than likely be an asterisk based system for initial testing as I've had great luck getting faxing to work on those where many people said it wasn't very reliable. Never had a problem. Once things are working, I might also use something like an Octel server or a MultiTech, haven't really decided just yet. Thought I would get the routing going first to something I've got on hand, then decide what I'll use for fax server. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/ _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
