Maximum number of Unity Voice mail users on MCS7825I1

Hi ,

Can some body tell me the max number of unity voice mail boxes I can have on the MCS-7825I1 server. Using the config tool I can configure max 500 voice mail ports for user. Whats the solution to get arrox 1000 voice mail boxes for users ?

Engineering answer depends.

This link;

states that a 7815 can do 1000 mailboxes voicemail (on or off box) or unified messaging (off box). Its 500 if you do IMAP or Groupwise clients (these require off box). I ran a voicemail only config through the product configurator and it passed so I don't think you are seeing a configurator error. Here is that configuration:

Re: Maximum number of Unity Voice mail users on MCS7825I1

You can only have 24 voicemail ports for this server; I think this is the limiting factor. You will probably set aside one or two ports for Unity Dial-Outs. So that leaves you with a maximum of 22 simultaneous sessions to Unity for 1000 subscribers.
