  • Difference between DVM and HQ?

    I have seen the abbreviations HQ and DVM used and I have a few questions about these.

    1. Do these both refer roles that would be installed on a Dell or HP server?

    2. What does DVM stand for, and what is it used for?

    3. If we have a single site, would the DVM role and the HQ role typically reside on the same server (or is it not necessary to have a DVM if there is a single site)?

    Obviously I am a newbie when it comes to Shoretel, but I am trying to learn as much as possible in this month.
    I also have the most recent question in this thread in case you can help on that one.

    HQ means the headquarters server. DVM means distributed voice mail server. These are servers, not roles on a server.

    You do not need a DVM to use ShoreTel. The primary purpose of a DVM is to reside at a remote site and provide voice mail services when your WAN goes down (and thus your HQ server is unreachable).

      DVM (actually, they were renamed DVS - DVM is the old name that the guys who have been around still call it) servers can also be leveraged at HQ.

      Depending on the size of HQ, DVS may be required to house mailboxes and facilitate PCM traffic. There is a limit on the number of mailboxes and PCM instances that can be handled on a single server.

      Additionally, in very large designs (either a LOT of people or a lot of sites), DVS servers play a role in architecting around the Distributed Routing Service (60 or more SG switches).
