DPH-80 Phone User Manual
SIP
Troubleshooting
Phone book:
This feature allows the phone to be used without a SIP server. A set of 10
numbers can be programmed to the phone and the phone will directly contact these
numbers without the help of SIP server.
Remote diagnosis:
The SIP phone will send status and other messages to the log server
configured in the SIP phone. The remote log server should run the server application
from D-Link to receive and display these messages. This feature can be disabled
through the browser.
Restore factory defaults:
If you enter the specified key sequence, the SIP phone restores
the configurable parameters to default values upon next restart.
Production testing:
If you enter the specific key sequence, the D-Link SIP phone will
execute a production test upon next restart. The production test is described later in
this section.
Error Conditions
The D-Link SIP phone detects the following error conditions and plays error tone.
Error tone on network connection failure:
It will come to normal state upon network
connection. The link LED also gives this information.
Error tone if there is no DHCP server:
The phone will recover on detecting a DHCP server.
Error tone if the SIP proxy is down on power up:
The phone will recover on detecting a
SIP server.
Error tone if the called party is not registered.
SIP Troubleshooting
Some of the common error situations are described below.
Power up
No tone on power up:
Check the power adaptor and power source, and restart the
phone.
No dial tone on power up:
The SIP phone takes time to exchange information with DHCP
and SIP proxy servers. During this time it will play
call progress tone
. Then the tone will
change to
dial tone
if the exchange is successful or to
error tone
if it is failure. Wait for
the tone to change to
dial
or
error tone
.
Plays error tone on power up:
It means that the information exchange with DHCP or SIP
proxy server has failed. Check if you have a network connection and DHCP and SIP
proxy servers are running. Also, check if the SIP phone is configured properly. Restart
the phone and check it.
Making call
The SIP phone powered up properly but plays error tone while making call:
Check the
network connection and default gateway if they are working fine.
Plays call progress tone:
SIP phone plays call progress tone while trying to establish call
and it can take time. If it takes long time check if the SIP proxy server is running
properly.
Plays error tone:
The called party may not be registered with the proxy server.
Plays error tone after a long time:
The proxy server may not be running and the SIP
phone times out before playing error tone. It can take some time.
