Cisco Cisco Customer Voice Portal 8.0(1) Design Guide

For UCS performance numbers, refer to the Cisco doc-wiki link:

In all of the above scenarios, the Reporting and Datafeed options were disabled. Also note that:

Cisco IOS Release 12.4(15)T5 or later release is required on the gateway to support the HTTPS 
option. (Mainline Cisco IOS currently is not supported.)

Cisco recommends the following configuration on the Cisco IOS VoiceXML Gateway with HTTPS 
option. Not having this configuration setting can severely impact the performance and sizing of the 
VXML gateway and the overall solution in general with HTTPS.

http client connection persistence

http client cache memory pool 15000

http client cache memory file 1000

The following call rate calculations pertain to the MCS-7845-I3-CCE2 server.

The following components can be installed on the same physical server (co-resident):

Unified CVP Call Server (Call Server)

Unified CVP VXML Server (VXML Server)

Media Server

A SIP-based co-resident server can handle 1200 SIP calls as well as 1200 VXML Server sessions 
simultaneously, and it can handle a sustained call arrival rate of 14 calls per second.
