Resilient phones do not
fail over to their
secondary ICP when
their primary fails.
The network may not be
clustered or it may have
been improperly clustered.
To learn how to properly cluster a network, go to
http://edocs.mitel.com, and refer to
Voice Networking
-> Configure Network in the System Administration
Tool Online Help.
If you have clustered your network, verify that it has
been properly clustered. Using the System
Administration Tool on each 3300 ICP, verify that the
Cluster Element Index in the Cluster Elements form has
the same value as the PBX Number in the ICP/PBX
Networking form. (In the Remote Directory Numbers
form, look up the number of the phone or phones that
are not failing over. Note the CEID number for the
phones. Check the CEID numbers against those for the
phones in the ICP/PBX Networking form. The numbers
must match, and their values must not be higher than
256.
On each phone that is not failing over, use the debug
function to verify that its current ICP list contains a
primary and a secondary ICP.
On a 5140/5240 IP Appliance
1. Hold down both volume keys at the same time, and
dial 33284 (“debug”) to display debug options.
2. Press Network, and then press ICP Server IP(s).
Another set of options are displayed.
3. Check the options, starting at the bottom of the list:
- Press PBX Connection Info. The appliance should
display “PBX Connection Status TCP Link Active”,
which indicates that the appliance is in service and
communicating with its primary ICP.
- Press Current ICP Server to display the current
ICP address that the appliance is communicating
with.
- Press Current ICP Index. The appliance should
display “Current Server Index is:1, List Length is:
2" to confirm that the appliance has a list of 2 ICPs.
- Press IP Server Address 1 to display the IP ad-
dress of the primary ICP.
- Press IP Server Address 2 to display the IP
address of the secondary ICP. If the appliance is
resilient, it displays an IP address for its secondary
ICP. Verify that this IP address is correct. If the
phone does not display an IP address for a
secondary ICP, use the User and Device
Configuration form in the System Administration
Tool to provision the device with a secondary ICP.
