1) You can have 1 integration that uses Skinny (CCM or CME) but within that integration you can add multiple clusters.


2) You can have 1 voiceboard integration and 1 PIMG integration.


See the 4.0 Dual Phone System Guide for more info:

In Unity 4.2(1) this was extended substantially. See the 4.2 Multiple Phone System Guide:

With Unity 5.0, doc said Cisco Unity supports multiple simultaneous phone system integrations and are limited only by the number of licensed voice messaging ports. So. Does that mean if I have 144 Unity ports, I can have 72 integrations with 2 ports each?

You can have unlimited integrations in Unity 5.x, but once you max out 144 ports, you are done. In your example, that is correct.

Yes, that is correct.


You should consider though that the multiple integration feature of Unity is intended to offer a centralized voicemail solution in telephony environments that otherwise cannot support centralized vm. In a sense, Unity provides virtual voicemail servers for each phone system node that is not capable of connecting to a centralized server across the telephony network. Whenever possible, I would recommend interconnecting the nodes such that the need for multiple integrations is reduced. For example, if a trunk between node A and node B can be configured such that all voicemail traffic can be routed through node A, then this is preferable over having dedicated Unity connections at both nodes. Of course, this is not always possible (or economical), which is why Unity has the feature. But even collapsing 72 integrations into, say, only 36 will allow you to greatly improve the efficiency of the Unity ports.


Hope this makes sense,

Eric
