Voice Mail Ports; Enhanced Integration - Mitel MiVoice Office 250 Manual Book

MiVoice Office 250 Engineering Guidelines
In the preceding example, nodes 2-4 use node 1 as a PSTN gateway. Also, when nodes 2-4
call nodes 2-4, the call must go through node 1 to reach the other node. This typically would
be the case if the site used PRI trunks instead of IP networking for private networking.

VOICE MAIL PORTS

The v5.0 software release increases the maximum number of UVM ports from 16 to 32 as
follows:
• 24 UVM ports (maximum) on a standalone CS Controller (without a PS-1)
• 32 UVM ports (maximum) on a standalone HX Controller (without a PS-1)
• 32 UVM ports (maximum) on a CS or HX Controller equipped with a PS-1
NuPoint UM can also now co-exist with UVM. If a site has a combined voice mail port count of
up to 32 with medium call traffic, Mitel recommends that the system be equipped with a PS-1.
If a site has a combined voice mail port count of 24 or more with high call traffic, Mitel
recommends that the system be equipped with a PS-1.
Due to the limited number of compressed IP resources available on the Processor Module in
a CS Controller platform, Mitel recommends a PS-1 when equipping 32 ports of UVM. Note
that the HX Controller platform has more compressed IP resources so it can provide enough
resources for 32 ports of UVM; however, based on other factors like the number of IP phones,
the HX Controller platform may still require a PS-1.

ENHANCED INTEGRATION

If a site has more than 100 mailboxes with the Enhanced Integration enabled, Mitel recommends
that the system be equipped with a PS-1. Note that in this scenario, the UVM resides on the
PS-1 to provide more call control processing power.
Mitel recommends that when choosing the E-mail Client Message Format or the Download
Format for Mobile Web Page settings for E-mail Synchronization to use the default of value of
WAV instead of the MP3 because the MP3 encoding requires more processing time. This can
result in a delay in delivering the e-mail with the attached voice mail message when multiple
messages need to be delivered at the same time. For systems requiring a large amount of MP3
