Unity 4.2 desgin question

[david.mcguire]

Is there a limit on how many separate UCM (callmanager) clusters can be added to a single Unity 4.2 system?

Hi David,

Maximum Supported Combinations

Cisco Unity 4.2 supports a maximum total of 9 simultaneous phone system integrations with the maximum numbers described in the following sections:

Maximum Number of Phone System Types

Cisco Unity can integrate at the same time with all four of the phone system types that UTIM supports:

•SCCP (Cisco Unified CallManager and Cisco Unified CallManager Express only)

•SIP (including Cisco Unified CallManager and Cisco Unified CallManager Express)

•Circuit-Switched via Voice Cards

•Circuit-Switched Phone System via Intel PIMG

Hope this helps!
