The dial pad does not work. The dial pad on the
Polycom CX700 IP phone does
not respond. Do one of the following steps:
• Check for a response from other
feature keys or from the dial pad.
• Place a call to the phone from a known
working telephone. Check for display
updates.
• Check the termination at the switch or
hub end of the network LAN cable.
Ensure that the switch/hub port
connected to the telephone is
operational (if not accessible, contact
your system administrator).
• Before restarting your phone, contact
your system administrator, since this
may allow more detailed
troubleshooting to occur before losing
any current status information.
