Hi,
In my experience never use more than one PCI card be it PRI or FXS/FXO on a
system with that low power. I have seen that offloading FXS/FXO operations
to SIP based media gateways (e.g. AudioCodes MP118 4FXS-4FXO) will enable
you to conserver power. Since they have embedded g729, if you also ha

If you shop around you should be able to find either new Polycom 320's
or perhaps some used or refurbished Polycom's or Cisco's for very
reasonable prices. I'd suggest contacting a reseller and telling them
you're looking for used or refurbs. I know I've gotten some open box IP

Thanks for all the advice, everyone.
Noted the FXS power issue. As for cost of channel banks versus PCI
cards, I was looking rather at something like the Rhino board:

Hey Tom,
You won't be able to fit 3 24x FXS ports into a single system because
you will need too much power to supply ringing to your phones connected
to FXS ports.
The Mediatrix 1124 is about $1,600 brand new. The Digium 24 ports ePCI
card sells for $1,530 at VoIP supply. The Sangoma 24 por

Please be advised that running 72 FXS is a "power killer" requirement.
FXS lines have to provide the power to the analog phones and you have to

Would this not work out more expensive than getting some internal

something else as being more reliable/better quality (Sangoma/Rhino?).

Hello all
I've been setting up some remote offices with net5501s, containing a
combination of TDM cards for POTS lines and ISDN BRI cards. I'm using
Snom SIP phones.
Our head office requires a bit more thought. It currently has an ISDN
PRI and three analogue lines, which I could handle in the sam
