<DIV><FONT size=2>That being said, with respect to the servers, the Cisco site
has plenty of information on hardware content as well as the total number of
phones supported per server. It all depends on your comfort level with the
availability and serviceability of the servers. For example, the 7825 doesn't
have dual/removable power supplies.</FONT></DIV>

<DIV><FONT size=2>As for the gateways, you have to look at functionality here.
MGCP vs H323 (or at least that's what I hear ;) and configuration. We use the
old 6608s for T1 connectivity as well as conferencing and I love them. But we
lose out on some of the feature sets like VXML and some of the fancy Tk/tcl
things that people can do on routers. If you already have the 6500s, I would say
get the CMMs.</FONT></DIV>

recommendations</DIV>
<DIV><BR></DIV>My organization is preparing to move from a traditional PBX to
a Cisco<BR>IPC system and has been given contradicting recommendations for
certain<BR>equipment by different potential vendors. What are your pros,
cons, and<BR>recommendations for these pieces:<BR><BR>Gateway between internal
network and PSTN:<BR>2 Cat6500 Communications Media Modules (installed in
separate core<BR>6500s) w/ 6-port T1 adapter<BR>vs.<BR>2 3845 ISR voice
bundles w/ 3 PVDM2-64 DSPs, 2 2-port T1 VWICs, and 2<BR>4-port FXO VICs each
<BR><BR>CallManager servers:<BR>MCS-7825 v. MCS-7835<BR><BR>Our environment
will have 675 phones at time of install with projected<BR>growth of 250 phones
in the next 5 years, and 4 T1s for PSTN interaction<BR>(2 DID, 1 WAT, 1
other). Important to our consideration are redundancy,<BR>performance,
ease of configuration and management, scalability,
and<BR>cost.<BR><BR>TIA,<BR><BR>Matthew Brown<BR>High Point
