3300 ICP Technician’s Handbook
While on a call at a
resilient phone, the
primary ICP goes out of
service, and the call is
immediately dropped (no
call survival). After you
hang up the IP phone
and go off-hook again,
the IP phone remains out
of service.
Refer to the 3300 ICP Resiliency document on Mitel
OnLine for corrective action.
After an IP phone fails
over to its secondary
ICP, you can make calls
from it, but other TDM
phones, trunks, or IP
devices in the cluster
cannot call it.
Refer to the 3300 ICP Resiliency document on Mitel
OnLine for corrective action.
After the primary ICP is
returned to service, the
IP phones do not fail
back to the primary. If an
IP phone is on its
secondary ICP, you hear
beeps every 20 seconds,
and the phone displays
"Fail <ICP IP address>".
Refer to the 3300 ICP Resiliency document on Mitel
OnLine for corrective action.
Message waiting
indicator on a resilient
phone continues flashing
for a Callback message
that has already been
returned.
Refer to the 3300 ICP Resiliency document on Mitel
OnLine for corrective action.
Hot desk users cannot

OnLine for corrective action.
