SL2100
An IP Terminal can send and receive RTP packets to/from another IP Terminal without using the DSP
resources on the VoIPDB. This operation only allows intercom calls between the IP Terminals.
If a digital multiline terminal or trunk is part of the call a DSP resource on the VoIPDB is required. If,
while on a peer to peer call, a conference call is initiated, the peer to peer connection is released and
a new non peer to peer connection is created using the VoIPDB. If the third party drops out of the
conversation, the call reverts to a peer to peer call (silence may be heard while this conversion is
made by the system).
Although the peer to peer feature is supported for IP Station-to-IP Station calls, the SL2100 chassis
must still have a registered VoIPDB installed in the system.
With Barge-In, a short silence may be heard if the following occurs:
• A peer to peer call receives a Barge-In without a Barge-In tone.
I
• A peer to peer call receives a Barge-In with Monitor mode.
• When the established Barge-In is disconnected.
• Peer to peer is a programmable feature that may be enabled or disabled (Program 15-05-50).
System Tones and Ring Tones
IP Terminals do not use PRG 80-01: Service Tone Setup entries. The tones are generated locally by
the IP Terminal. When a Door Box chime rings an IP Terminal, the system activates the chimes using
a ring command. Because of this, if the volume is adjusted while the door chime is sounding, the
ringing volume of the IP Terminal is also adjusted.
Music on Hold
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 SL2100 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
