I have a fax server vm setup and software which is the sr140 talks to the gateway which has two analog lines but for some reason,its not able to to route because it can't get the did info and my faxserver software vendors are blaming it on the nortel pbx side. We have nortel cs 1000. What needs to be done on the nortel side to make this happen.

The analog lines need to be set up as TIE or DID. This is how I set up one: http://www.ghtrout.com/files/Connecting_a_DID_Fax_Server_to_CS1000.zip

Thank YOu ghtrout. Can you explain what tie is and could you explain the diagram you sent me. I would have to send it to my telephony team. I am the it admin trying to set this up.

I would send my document to the person that manages the Nortel. The most basic explanation is that TIE lines repeat digits

Chrismatt83..... You say that you have 2 x analog lines. Do you mean analog extensions or COTs or TIEs?

This becomes important in any response.

So basically we are doing our first fax server project and i'm part of the sys admin group and I don't have a clue on how telephony works and have to work in tandem with our telephony team who is not really cooperating. So basically on my fax server i'm not getting caller id info and hence it is unable to route to the appropriate user. I was given two analog lines (rj11) that plugs into a dmg 1008 gateway device as part of the test. The other end is connected to the pbx. I was given two did numbers associated with those two lines. Not sure on what COTs or TIE's are. I was able to send faxes but not receive. When a fax is sent it gets stuck in a queue since something on the pbx needs to be setup to get the did info so that the fax server can route the info to the two analog lines. So i need the telephony team to cofigure the pbx to get did digits info via dtmf. But the telephony team doesn't have a clue and told me to get a DMG2030DTIQ which is gateway that has a t1 interface. I'm trying to bypass this by doing research on my end when i should't have to..sigh!!

How about calling the manufacturer of the fax server and asking them how you would set this up? None of us know what they suggest.

I am still vague as to what you have, and it does seem as if your telephony dudes are not overly helpful.

IF you have analog extensions, then you can use a feature called FAXS. Basically you would set up a hunt group, or multiple groups, with the 2 x analogs as members. There is more to it, but that would then give you "inband dtmf". That means that when the analog answers the call, the PBX pushes out DTMF towards the fax server. The DTMF would then be the the ID of the hunt group pilot, and thats how you discriminate the number called.

Other solutions such as PRI, LSE1 etc are effective, but do not seem to fit in with what you are describing.
