ISSUE 2.0
Music on Hold is also provided by the IP Terminal. The settings in PRG 10-04: Music on Hold Setup
are ignored except to determine whether or not music should be provided. If PRG 10-04-02 is set to 0,
music on hold is not heard. If PRG 10-04-02 is set to 1 or 2, music is provided by the IP Terminal.
Registration Mode
The has three types of registration for IP Terminals, Plug and Play, Automatic, and Manual
programmed in PRG 10-46-01:
• Plug and Play mode - when the phone boots up it reports the extension assigned in the phone or
chooses the next available extension in the system. No password is required.
• Automatic mode - the SIP user name and password must be entered in the actual IP Terminal. The
phone comes up as the extension associated with the user name and password is entered.
• Manual mode - when the phone boots up it prompts the user to enter a user ID and password
before logging in. If a user ID and password are set in the SIP User settings of the phone, as with
Automatic mode, the phone does not prompt for login. This allows some phones to come up
automatically and some phones to prompt for login. In manual mode, the phones that do not have a
user ID and password set in the phone are prompted to log in. A user can also logoff the IP
Terminal to allow another user to login with their own user ID and password.
To logoff the IP Terminal:
Press the Down Arrow Softkey, press the Prog Softkey, and then press the LOGOFF Softkey.
Multiple Logon
The same user name and password can be assigned to multiple extensions when using Automatic or
Manual Registration. This makes it easier on the user by only having to remember one password. For
example, if a user has an IP Multiline Terminal and uses Desktop Applications with the Enhancement
bundle controlling the IP Multiline, three different ports are used in the system. Even though all three
can be assigned the same user name and password.
Registration Override
When Manual mode is used, Registration Override can be used. Registration Override allows a user
to login at one phone, and later login at another phone and keep the same extension number. This is
useful in the case where an office user has an IP Multiline Terminal at work and at home or a
Softphone they use on the road. They log in at work to use the office terminal, and when they get
home or are on the road they login the home terminal or Softphone. When this happens the office
terminal is logged out and they have the same extension number at home or on the road.
System IP Terminals and Analog Trunks
Due to the nature of analog-to-digital conversion, considerable echo may be encountered when using
Analog Trunks with IP Terminals.
• In every system that has analog trunks and IP Terminals PRG 90-68 (Side Tone Auto Setup) must
be run per trunk to minimize any echo problems.
• Due to all Analog trunks being different, padding of the Analog Trunks in PRG 81-07 and PRG
14-01 may be necessary. Even after the pad changes are made, an echo may still be present the
first few seconds of the call while echo cancellers are learning the characteristics of the circuit on
this call.
• For best performance, it is recommended to use digital trunks when using IP Terminals.
Digital (ISDN, T-1, and SIP) trunks do not suffer from this problem.
Conditions
• The voice quality of VoIPDB depends on variables such as available bandwidth, network latency
and Quality of Service (QoS) initiatives, all of which are controlled by the network and Internet
service providers. Because these variables are not under its control, NEC cannot guarantee the
performance of the user's IP-based remote voice solution. Therefore, NEC recommends connecting
VoIPDB equipment through a local area network using a Private IP address.
