Assuming the CMMs are going into existing core 6500's, would that put more dependancy on network upgrade schedules etc? For instance if you need to reboot your sup card in the 6500 for something unrelated to voice, wouldnt it take down your gateways as well. On the other hand, it would probably be easier to manage if its just another part of a core box.
<br><br>If all you will ever need is 4 T1's it might be better to get the 3845's with redundant power supplies - i have no idea how the prices break down.<br><br>For the record I like the 6608's too :)<br><br>I would get the 7835's if you can afford it for the hotswappable parts. I think the 7825's now have SATA RAID 1.

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Always go with a 7835 over a 7825.
unless the 7825 has RAID 1 mirroring which the older 7825 didn't. we
use a 7835 as the pub and 7825 as the sub. </span></font></p>

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">We have the CMM in our Cat65xx and I love
it. I have also used some 28xx series routers. As far as easy there
isn't much difference both run IOS. MGCP is going to be the easiest but
you might need H323 if you are integrating with any old PBXs. If you want
the most scalable I would use the CMM as you can put high port density on the
CMM. 24 FXO, 6 T1, and Conferencing / transcoding resources and you can get up
to 4 of those cards in a single blade. We use both the 6 port t1 and ACT
cards.</span></font></p>

with one over the other. Let them do the work is what I say. ;)</span></font></p>

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.</span></font></p>

<div>
<p><font face="Times New Roman" size="2"><span style="font-size: 10pt;">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.</span></font></p>

<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">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>
