Question
There is no dial tone.
I cannot dial out.
The Speed Dial key does not work at all.
Suggestion
• Try all the above suggestions.
• The Cat-5 network cable may be defective.
Install a new Cat-5 network cable.
• Make sure your network is providing Power
over Ethernet (PoE).
• Disconnect the telephone base from the
network wall jack and connect a different
working SIP telephone. If there is no dial
tone on this telephone either, the problem
is in your wiring or network server. Check
your SIP server settings and refer to the SIP
Phone Configuration Guide for details.
• Make sure the initialization and system
registration process completes (pages 10
and 13). The speakerphone key blinks twice
every second if there are errors with the
initialization and system registration process.
Check your SIP server settings. Refer to the
SIP Phone Configuration Guide for details.
• Make sure the energy-saving charging mode
is not activated. If this mode is activated, all
telephone functions will be disabled, except
battery charging (page 13).
• Try all the above suggestions.
• Make sure there is a dial tone before
dialing. It is normal if the cordless handset
takes a second or two to synchronize with
the telephone base before producing a dial
tone. Wait an extra second before dialing.
• A prefix may be required for dialing some
internal or external calls. Refer to the SIP
Phone Configuration Guide for details.
• Check your SIP server settings. If other SIP
telephones in your hotel are having the
same problem, the problem is in the wiring
or network server. Contact your telephone
service provider (charges may apply).
• The Speed Dial key may not be properly
programmed. Refer to the SIP Phone
Configuration Guide for details.
