Multiple Instances of Unity and or CCM

Does anyone know what limitations Unity 3.1.(5) (or 4.0(1)) has regarding multiple connections to CCM and visa versa.

Without failover or Clustering CCM, how many Unity servers can you connect to one CCM.

With a single Unity server how many CCM servers can you connect at one time.

Is it limited due to Voice mail Buttons, TSP & MWI problems that currently exist or is there a new TSP for 4.0(1) which allows this.

Thanks for any help/advice you can provide

Re: Multiple Instances of Unity and or CCM

Unity connects to CallManager using the SCCP (Skinny) protocol. IP phones use the same protocol to communicate with CallManager. As far as CallManager is concerned, Unity is basically an IP phone.

Different versions of CallManager installed on different platforms support different quantities of total devise weight. One Unity port is equal to the weight of one IP phone line.
