G566 andG266:
The G566 and G266 operate as standard SIP devices when connected to a SV9100.
The line keys on the G566 are not functional in this application.
Powering the AP400/AP300
The AP400/AP300 can only be powered using Power over Ethernet (PoE) 802.3af. A
PoE switch is a switched hub that also provides power over the spare pairs. The
switch can be used with other devices than the IP telephones and detects whether or
not power is needed. Using a PoE switch makes it easier to protect the IP telephones
from loss of power (connection of the PoE switch to an UPS).
Updating the AP400 and ML440/G566/G266 System Firmware
The firmware on base stations and handsets is updated remotely using the HTTP
configuration interface to download firmware files from a TFTP server. Updating base
station firmware involves an automatic reboot of the base station at the end of the
firmware download. This will drop any active calls and in addition updating the
handset firmware can take several hours. It is recommended updates are performed
after normal business hours.
REFERENCE
IP Multiline Telephone (UT880)
The UT880 is a VoIP desk phone that runs the UT880 MLT Multiline Telephone
Application for use on the SV9100 system. This phone is powered by Power over
Ethernet (PoE) reducing the need for power adapters allowing for a clean installation.
In addition, for those users who frequently make long calls the UT880 provides
headset support for added comfort.
The UT880 can only be powered using Power over Ethernet (PoE) 802.3af.
IP Single Line Telephone (SIP)
SIP (Session Initiation Protocol) is used for Voice over Internet Protocol. It is defined
by the IETF (Internet Engineering Task Force) RFC3261. Other RFC designations,
such as RFC3842, refer to a later implementation of SIP and may be supported by
the UNIVERGE SV9100. Commonly called SIP Station, this feature is used for IP
Stations using SIP.
SIP analyzes requests from clients and retrieves responses from servers, then sets
call parameters at either end of the communication, handles call transfer, and
terminates. Typically, such features, including but not limited to Voice over IP
services, are available from an SIP service provider.
