(I.) Need to provision a Voice Gateway for a Single Site with 10000 Users
I have taken Cisco 3945:
Assuming 5% of Concurrent calls = 500 (5% of 10,000)
No. of T1s required:21 (24 Channels * 21 T1s = 504)
Please advice if this is a fair assumption for considering No. of T1s considering if no other information is given other than total number of users
Should I take T3 instead of T1 in such a scenario?
Should DID and FXS be also assumed ?
(II.) UC on UCS
Total Users 10,000
Is option-1 or Option-2 better for redundancy
(1-VMware supports 7500 Users)
(1-UCS-B200M1 Blade Server can have max. 4 VMware)
Option-1: One UCS-B200M1-Blade server with 4 VMware
Option-2: Two UCS-B200 Blade Server with 2-VMware each
