13.3 IP Phone Registration Modes
The SIP MLT supports three different registration modes.
• Plug and Play
• Automatic Login
• Manual Login
Plug and Play Registration
Plug and play registration mode allows for no authentication. As long as an IP terminal is configured
with the proper IP addressing scheme, and plugged into the network, the phone comes on-line. In plug
and play mode you may assign an extension number into the IP terminal or allow the system to
automatically set an unused extension number for the station. When the system assigns unused
extension numbers it starts searching for the first available port or starts at a preassigned port and
works its way up from there.
Automatic Login
When set to automatic login the SIP user name and password must be entered in the configuration in
the IP terminal. When the phone tries to register with the CPU it checks the user name and password
against its database. If the user name and password match, the phone is allowed to complete
registration. If the user name and password do not match, the phone cannot register with the CPU.
The IP terminal displays an error message:
Unauthorized Auto Login .
Manual Login
When set to manual login, no user name, password, or extension number is entered into the
configuration of the telephone. The user is prompted to enter this user name and password into the IP
phone. This information is cross referenced in the phone system to an associated extension number. If
a match is found, the phone comes online. If there is no match, the phone cannot complete
registration with the CPU. The IP terminal either returns to the login/password screen, or locks out the
user and requires the administrator to unlock the IP terminal. Lockout on failed attempts is dependent
on system programming. Manual mode is good for an environment where multiple users share the
same IP phone at different times. As one user logs out the next user can login with their credentials
and all of their associated programming follows.
In Manual mode a user can also logoff the IP phone to allow another user to login with their own login
ID and password.
To logoff the IP Phone when the terminal is set to "Standard" softkey mode (PRG 15-02-60) use the
following operation: Press the "Prog" softkey, press the "Down Arrow", press the "Down Arrow", press
the "Down Arrow", and then press "Logoff". The IP Phone can also be logged off by resetting the IP
terminal.
To logoff the IP Phone when the terminal softkey is set to "Advanced Mode 1/2" (PRG 15-02-60) the IP
terminal must be reset.
Encryption
The SL2100 Supports AES 128-bit encryption between 8IPLD terminals and the VoIPDB.

terminal the voice cannot be encrypted.
