Question Suggestions
2. here is no dial tone.
• 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. 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.
3. I cannot dial out.
• 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).
