- Hi. I was wondering if anyone out there knew of any modems
- that support E&M signalling. This capability, along with
- support from the CO switch or PBX, allows the modem to
- determine what the called number is. It requires 4 wires
- to the switch, instead of the usual 2.
-
- Note this is not caller id, where the calling number is
- transmitted, but rather getting the called number. This is
- very useful if the PBX was programmed to route several destination
- numbers to the modem, and you wanted the computer's software to
- act differently depending on which phone number the originating
- actually called.
-
- I'd prefer a modem that supported v.32bis and FAX, but right I'm
- just interested in any modems that support this at all.
-
- Thanks,
- Milo
