All,
We're pondering the possibility of upgrading our CS-5200 to a Mitel 3300 MXe II and 5330 phones. We currently have seperate CS-5200 deployed at 5 locations. With the 3300, we're thinking about a single unit, with a possible secondary unit at our backup DR site servicing all of our 5 locations. We're approxmately 100 extensions total. Primary drivers are the pure SIP enviroment and integrations with MS OCS 2007 / Exchange 2007. This looks like a super sweet setup on paper, but I haven't had much experience with it, so I would appreciate thoughts/comments/suggestions from the more edumicated out there. FYI: Our WAN is a Level3 MPLS backbone with DS3 servicing our DataCenter, and T1 connecting our remote offices, utilizing a 100% Cisco infrustructure with QOS.
1) Redundancy / DR Purposes - Is it possible to place a secondary unit at a remote location as a failover unit should the main unit go down? How redundant/automated could this be -- will the phones automatically switch from the primary to the secondary controller?
2) Office Communication Server 2007 / Exchange 2007 Integration - Any one accomplished this? Thoughts/Comments? I've spec. the Live Business Gateway on the Application Process Card for this. I'm looking to tie presence information, as well as give the users the ability to dial directly from Outlook. I would also utilize this as as a Softphone for a few users. Anyone got inbound faxing to work with Exchange?
3) Duplicate extensions - How does the 3300 handle duplicate extensions? Currently, with the CS-5200 I must configure a hunt group to give a user multiple handsets.
4) Automated Attendant(s) - Since I'm forsaking the Mitel UM server(s) for Exchange 2007, will my exchange handle Automated Attendant (Intertel Application) functions?, or do I at least need a basic VM for this? Most of what I have is mainly STARs, and Overflow apps (we're currently busy - please kiss our butt...we'll be with you shortly
, and an "On Hold app" described below.
5) "On-Hold App" - Calls to extensions that are in DND are immeadately sent to VM. Calls that are sent to extensions that are busy greet the caller with an option to continue to hold, press 1 to leave a VM, or )0 for the operator. Currently this is accomplished utilizing dedicated System Fowards for each extension, dedicated Call Routing Apps for each extension, along with a seperate single extension hunt group for each extension. (Talk about a pain in the arse). Since Exchange 07 interfaces with the CS-5200 via an analogue trunk, this I can't send callers from a CRA directly to a VM mailbox (the CRA doesn't pass the called extension info through the analogue VM trunk group). Is this going to be the same in the Mitel System since Exchange is utilizing a SIP trunk?
6) Faxing: Currently (on my 5200) DIDs ring to a CRA that does fax detection and send the fax through the Inter-Tel UM server to the users email, or sends the call (default time out) to the appropriate extension. Any comments on how this will work with Exchange 07? What does everyone recommend to interface a POTs fax machine at a remote office over the WAN (SIP adapter)?
7) SIP Trunking - Anyone have any experience, thoughts, suggestions with Bandwith.com? I'm considering replacing my PRI's at each location in favor of a SIP trunking.
I appreciate any insight anyone may provide to these questions.
Thanks!
