With a couple other PBXs I've worked on I've been able to integrate with an analog fax server by simply sending DTMF digits of the called station when the fax server goes off hook. I've also used the same for connection to an analog integrated voicemail. We have a lot of older G3 Definitys. I wonder if these vintage systems can do that application? I searched on "Fax Server" in some documentation that I have with no luck yet. If it's like others I've done, a subscriber's coverage path is to a hunt group. The members of the hunt group are analog lines configured specifically to ring the voicemail/fax server, when answer supervision is detected the called number will then be outplused via DTMF. I wonder if this can be done on our vintage systems?
