Trouble Shooting

5.1.1 No information on the display

Check that the power adaptor is plugged into the IP phone and into the mains.

5.1.2 Failure to register with the Advantage system

If the display shows the message "Failed to register with Server. Check Extn name & PIN",
Press the Menus key and verify that the following are correct:
- 'Registration Info', select and check that the Extension Name and the Extension PIN are
correct, paying particular attention to maintaining capital letters, small letters and spaces.
Local IP Parameters
-
If the Advantage system is remote (i.e.) the connection is over the public Internet
o
If the Advantage system is on the local LAN
o
If there is no DHCP server active to allocate an IP address to the Advantage IP
o
Executive, then the DHCP client in the phone must be set to disabled and the IP
address entered manually. In this case check that the IP address, which has been
entered manually in the phone, is within the same address range as the local router.
Server IP parameters
-
Check that the IP address of the Advantage server is entered correctly. You may
o
enter a second server IP address under the menu option' Change Alt. IP'. This
allows both the local LAN IP address and the public Internet IP address of the
Advantage server to be entered on the phone. This will facilitate the connection of
the phone either locally on the LAN or remotely across the Internet.

5.1.3 Echo during speech

If there is persistent echo on the line that interferes with normal conversation and that does not
go away after the first ten or fifteen seconds of a call, check with your network manager or
dealer to ensure that an Applications card with sufficient IP channels is installed at the
Advantage system.

5.1.4 Loud noises, clicking or interruption of speech

IP traffic is subject to a level of noise, depending on the configuration conditions and traffic on
the network. Persistent levels of noise that interfere with normal conversation can result from
absence of appropriate voice compression or failure of quality of service mechanisms. In any
case, consult with your network manager or dealer to ensure that an Applications card with
Quality of Service and sufficient IP channels is installed at the Advantage system.

Check that the following ports in the local firewall are open:

50000 for UDP packets (for speech)
50001 for UDP packets (for speech)
Check that the Advantage system and the Advantage IP Executive phone
are in the same IP address range and also connected to the same LAN.
