IP Phone Registration
1. Record the error message on the IP Phone display, then go through
Table 27 below.
2. If you still can’t fix the problem, call Mitel Technical Support.
Make sure you have the following information on hand before calling:
 Is the problem with the local or remote subnet?
 DHCP server(s) settings
 Layer 2 switch configuration and settings
 Router configuration and settings
 Network Diagram
 IP addressing scheme
 VLAN configuration and settings
Tip: To rule out DHCP problems, and isolate network-related issues, we
recommend that you program the IP Phone with a static IP Address (see
“Setting Static IP Address on IP Display Set” on page 54).
Note: IP sets require a firmware upgrade to support the new DHCP options
introduced in Release 7.0; otherwise, the sets will fail to boot. Such failures
can occur, for example, in a resilient cluster of mixed software releases
or when sets with old firmware are added to a controller after it was
upgraded to Release 7.0. For the sets to boot, DHCP options 128-133
must be present in the DHCP server. After the sets have booted, options
128-133 may be removed to avoid future conflicts with standardized or
other vendors’ use of these options.
Tip: Use the debug option on display IP phones to view Version, Network,
Telephony/DSP, Connection Browser Config, and memory Stats details (see
page 170).
