Special Considerations for Mitel Endpoints
Consider the following before installing the Mitel IP endpoints or upgrading to v2.4:
• Inter-Tel highly recommends that systems running Basic Voice Mail (BVM) upgrade the
CompactFlash
®
card to either 512MB or 1024MB before upgrading to v2.4.
• When upgrading Inter-Tel 5000 software versions, Inter-Tel recomments that you do not
use a wireless network connection because a wired connection is less likely to interrupt
the upgrade.
• The Mitel Models 5212 and 5224 are not suported for remote/teleworker locations.
• When using a Mitel Model 5330 or 5340 from a remote/teleworker location, make sure port
69 is open on the corporate firewall to allow communication to Inter-Tel 5000 server.
• Mitel IP endpoints use DHCP option 128 for TFTP communication and DHCP option 129
for the call control address. Inter-Tel IP endpoints use DHCP option 66 for TFTP
communication and UDP discovery (broadcast) for the call control address (.cfg file).
• DB Programming provides the option to convert existing Inter-Tel endpoint extensions to
Mitel endpoint extensions.
• Preprinted paper designation cards are available for the Models 5212 and 5224.
