General requirements 51
The number of users the OCS Proxy server with MCM can handle depends
on the usage and the number of calls per hour per user. For example,
assuming 5 cph/user for VoIP calls would give 3000 users (15 000 cph/5
cph/user = 3000 users).
The following are the formulas (based on SPECint_rate2000) to calculate
the maximum call rate for different platforms:
•
VoIP calls only. Number of calls per hour supported = (15 000 x SPECint
of HW) / 29.8.
•
SIP CTI (TR/87) RCC calls only. Number of calls per hour supported =
(10000 x SPECint of HW) / 29.8.
•
Both VoIP and SIP CTI (TR/87) RCC calls combined. Number of calls
per hour supported = [(15 000 x SPECint of HW) x (VoIP_call%) + (10
000 x SPECint of HW) x (SIPCTI_call%)]/ 29.8.
ATTENTION
VoIP_call% or SIPCTI_call% must be less then 100%.
ATTENTION
An OCS Proxy is not an Access Proxy. For more information on OCS proxy
hardware requirements, see Table 8 "OCS Proxy server hardware requirements"
(page 53).
