Hi,
The Cisco phones we use at work use Cisco Call Manager to control them and the SCCP "skinny" call protocol. They are 7900-series phones and the only two options (selected by which firmware binary the phone picks up by TFTP when it boots) I'm aware of are SCCP and SIP.
If you have a Cisco download centre account you should be able to download both sets of binaries.
We have a Cisco softphone app too (don't know if there is a Linux version).
Cheers,
Paul.

There are a bazillion good softphones available - but we need to check
your needs first to see if there are any that will work for you...

Are you *sure* about this?
MGCP is a Gateway Control Protocol (as the acronym tells you). It can
encapsulate SDP and RTP, but it's more aimed at the link between a VoIP
network and PSTN. That's not to say that you haven't got MGCP to the
phones - but a cursory search didn't turn up any phones that do that...
If, on the other hand, you have SIP phones (which Cisco have been selling
for donkeys' years), your life will be very much simpler.

Can you find out which model of phone you use (any example off any desk
will do), and if possible, what your VoIP installation is?
Vic.
