I am working on a project where I am setting up an office of about 14 phones. I am trying to deturmine what TDM interface to use.
I was wondering if anyone has had any experiance with the external TDM interfaces like Xorcom or AudioCodes?
6 interfaces that I know a little about:
least expensive per port: 7 linksys pap2 sip ATAs
Xorcom – usb interface, kind of expensive, drivers are now built into asterisk source (so I hear) but your channel bank is part of the setup. UTAUG discount (may no longer work):
Digium – 24 port fxs card with amphenol socket. Full length card so you need a big case, gets rid of the need for a channel bank, pricey
Rhino – lowest price 1 port t1 card that can connect to a channel bank (tdm gateway device.
