We have an Mitel (Inter-tel) 5000 running 5.0 OS with an SLM-4 connected to a Perle multiport fax modem. We have a PRI providing our dial tone and I'd like to take advantage of some of our unused channels to give some of our staff personal fax lines like an eFax service.

My question is how can I configure my 5000 to forward the DTMF tones to the modem? I've only got a few modem ports available but I'd like to run 5-10 personal DIDs. My fax server software supports DTMF routing as does the fax modem, but all my reading hasn't been able to help me configure the 5000 to hand off something I can use to identify which DIDs are being dialed. Has anyone ever successfully attempted something like this? Or am I just wasting my time?
