Hi All,
I’m running Elastix 2 with FreePBX 2.7.0.6
The system is configured with a T1 (10 channels) and one 4 port FXS card.
The 4 ports on the fxs card are all hooked up an external fax server running a Mainpine 4 port modem board (analog)
I setup 4 zap extensions 701, 702, 703 and 704 and they all belong to ring group 700. Fax comes in the first available modem answers.
I set up my inbound routes for various fax numbers we have to terminate on the ring group. All this works very well without any issues.
My issue/Problem. Since the mainpine fax modems are analog I can’t pass the DNIS (the fax number they called). The fax modems do allow you to pass this information via DTMF and that’s what we did with our old pbx before we switched to asterisk.
I’m a bit lost on how to do with inside of freepbx and what files to modify. I did read over some docs and I came across the following:
SendDTMF(${CALLERID(dnid)},200)
But I’m still lost any help would be appreciated. My problem is we have to sort and store the incoming faxes based on the fax number called as we assign that to larger customers.
