Loss of PC network connectivity
through IP phone
If your PC is connected to the
network through an IP phone,
your PC network connection is
interrupted for approximately 1
to 2 seconds
• if the IP phone momentarily
loses power
• if you manually reset the IP
phone via the debug menu, or
• if the IP phone automatically
resets because it loses
connectivity to the 3300 ICP
for 10 minutes.
Note: If a resilient IP phone fails
over to its secondary controller,
the PC does not lose network
connectivity.
None. Connection is automatically
restored in 1 to 2 seconds.
