IP Phone models

ESI Communications Servers support the IP Feature Phone II, Local IP Cordless Handset II, Local IP
[original] Cordless Handset, Remote IP Cordless Handset II, and Remote IP [original] Cordless Handset.
(See "ESI Cordless Handsets," below.)
The desktop IP Feature Phone II
but connects from within the local premises via an IP local area network (LAN) rather than twisted-pair cabling.
If used on-premises, the IP Feature Phone II derives its operating power directly over the LAN from Power over
Ethernet (PoE). If used remotely, the IP Feature Phone II connects to the cabinet from a remote location via an
IP network (either a WAN or the public Internet). Each IP Feature Phone II derives its power from an individual
Power over Ethernet (PoE) adapter. (As with the 48-Key DIgital Feature Phone, a backlit display is available.)
The IP Feature Phone II supports the following features and standards:
• IEEE 802.3af Power over Ethernet (PoE).
• Power via PoE.
• Can be configured for either local or remote (off-site) operation.
• Uses a G.711 codec in its "local" mode of operation and a G.726 codec in its "remote" mode. In G.711 mode,
the transfer rate is 206 Kbps; in G.726 mode, the transfer rate is 90 Kbps.

• Can use DHCP to obtain an IP address:
– In "local" operation, DHCP can be enabled or disabled
"static" IP address may be assigned by the Installer (in Function 31; see the ESI Communications
Servers Programming Manual, ESI document #0450-1050).
–
In "remote" operation, the IP Feature Phone II automatically uses DHCP to obtain an IP address and
default gateway.
• Complies with IEEE 802.1q and 802.1p (VLAN) Layer 2 switching and prioritization.
• Complies with differentiated services (DiffServ; RFC 2475) Layer 3 Quality of Service (QoS) implementations.
Notes: If connecting the IP Feature Phone II to a Power over Ethernet source, the PoE cable must be connected to
the jack labeled NETWORK on the base of the phone. The jack labeled PC does NOT support or provide
Power over Ethernet.
ESI has tested the IP Feature Phone II with several Power over Ethernet sources. For a current list of tested
devices, see www.esiresellers.com/PoE.
Important: The ESI IP Feature Phone II doesn't work with ESI's IP E-Class or IVX
Communications Servers (except the ESI-50L, which doesn't support IP devices). Similarly, previous
IP Feature Phone models (including the Remote IP Feature Phone) don't work with ESI Communications
Servers. Instead, they are intended for use with only IP E-Class and appropriate, IP-enabled IVX systems.
