<br>
Thanks for clarifying that.<br>
<br>
A bit of disclaimer: participation in this mailer comes with no warranty,

design guidance contact your Cisco account team.<br>
<br>
TFTP and IPVMS in general will consume less resources. TFTP mostly
requires memory and CPU for building and caching files in memory. IPVMS mostly
requires CPU for originating and mixing audio streams.<br>
<br>
<br>
Otherwise to your question:<br>
What would be the recommended architecture for subscribers?<br>
- Currently looking at having 3 x 7845 for Subs for about 7500 phones including
Softphones<br>
<br>
Option#1<br>
- 2 CCM Groups to have all phones split 50-50<br>
CUCM
Group1
CUCM Group2<br>
Sub
A
Sub B<br>
Sub
B
Sub A<br>
Sub
C
Sub C<br>
<br>
Option#2<br>
- 2 CCM Groups to have all phones split 50-50<br>
CUCM
Group1
CUCM Group2<br>
Sub
A
Sub B<br>
Sub
C
Sub C<br>
Sub
B
Sub A<br>
<br>
<br>
In Option #1 if SubA goes down then SubB is hosting all of Group2 and
concurrently attempting to register all phones from Group1. That could be a
bottle neck. It could cause Group2 to affect service for Group1. This
risk arises with only 1 failure (either SubA or SubB fails).<br>
<br>
In Option#2 if SubA and SubB fail then SubC has to register all phones. This
risk arises with 2 failures (SubA fails AND SubB fails).<br>
<br>
Regards,<br>
Wes<br>
