IP to IP calls OK, but not
IP to TDM calls (rings
once, then call drops).
E2T not loaded. 1. Verify that the E2T IP address is
programmed correctly.
2. Verify that the E2T IP address is
not used elsewhere on the
network.
3. If the E2T IP address was
hardcoded with a debug table,
verify its settings (see Table 77
on page 301).
All resilient IP Phones
are not functioning (no

Resilient phones do not
fail over to their
secondary ICP when
their primary fails.
Refer to the 3300 ICP Resiliency document on Mitel

Some resilient phones
are not functioning (no

hang up the IP phone
and go off-hook again,
the IP phone is
functioning on its
secondary ICP.
Refer to the 3300 ICP Resiliency document on Mitel
OnLine for corrective action.
