[cisco-voip] SRST Switching to Subscriber Site?

[Jorge L. Rodriguez Aguila]

The answer I guess is conditional. For a 100 Users you can keep a centralized deployment and do SRST. Putting a Callmanager Sub at this location will require you to Put a larger Pipe between this site and the HQ, as at least 1 Meg will be needed for ICCS between CCMs.  In terms of the Unity Box, It doesn't matter where the Mailbox resides as the Unity will pass the message into the Exchange cluster via the server he is homed to and will arrive into the mailbox of the person no matter which server he resides in. If you are indeed thinking about the Sub at the remote site you should keep in mind that you would still be passing the traffic along to the Unity box in the Central site unless you put one at the remote site as well, Otherwise if your Wan Link goes down, you will still have CCM capabilities but your calls routed to the AA will fail.

We have a site which is changing.  They are a remote site, currently operating as an SRST site, but their Exchange server (currently at the home office) is going to be moved to the remote location.  We have unified messaging and we currently have A Pub and Sub at our home office and a remote Sub at another office. Is it mandatory in such circumstances that we install a Call Manager and Unity box for this third site?  They have about 35 users - and may have as many as 100 in the next couple years.  Any suggestions?
