6. Trouble Shooting
6.1.1 No information on the display
Check that the power adaptor is plugged into the IP phone and into the mains. Alternatively that
the LAN actually supports Power over Ethernet
6.1.2 Failure to register with the Opera 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
o If the Opera system is remote (i.e.) the connection is over the public Internet
 Check that the DHCP Client setting is set to enabled.
 Check that the following ports are open in the local firewall:
5075 for TCP packets (allows registration and signalling)
Opera Flexicom/4.12em:
50000 for UDP packets (for speech)
50001 for UDP packets (for speech)
Opera 20IP/4IP:
50000 to 50031 for UDP packets (for speech)
o If the Opera system is on the local LAN
 Check that the Opera system and the Advantage IP Executive phone are in
the same IP address range and also connected to the same LAN.
o If there is no DHCP server active to allocate an IP address to the Advantage IP
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
o Check that the IP address of the Advantage server is entered correctly. You may
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.
6.1.3 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 sufficient VoIP channels are available: i.e. that an Applications card with
sufficient IP channels is installed in the case of the Opera Flexicom/4.12em system, or that an
expansion licence is in place in the case of an Opera 20IP/4IP with more than eight VoIP users.
6.1.4 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 Quality of Service is activated
