Using 48-Key IP Feature Phone II remotely

When used remotely (i.e., connecting to the ESI phone system over a WAN or the Internet rather than on a LAN),
a 48-Key IP Feature Phone II will operate like a regular ESI Feature Phone, with these important exceptions:
• Mode display — The bottom section of the phone's display will show RMT (short for remote) to indicate the
48-Key IP Feature Phone II's current mode.
• No 911/emergency calls — Because your phone isn't connected directly to your local telephone network, you
must use a regular phone connected locally, not the 48-Key IP Feature Phone II, to make 9 1 1 or other
emergency calls. (For more information, see ESI document #0450-0262, included with your 48-Key IP
Feature Phone II.)
Troubleshooting
Important: The audio quality of the 48-Key IP Feature Phone II is dependent on the quality of the connection between
the phone and the IP PBX at the main office. High data traffic on a poor or overloaded connection will cause
significant audio distortion, which may include pops and clicks, or warbling. In this case, contact your ESI
Reseller or network administrator for assistance. The quality of your main office's outside phone lines also
can affect the phone's audio quality. Due to the interface between advanced, packet-based phone systems
and the traditional public telephone network, a poor-quality phone line can degrade audio quality, causing an
echo on outside calls. An occasional echo isn't unusual and doesn't necessarily indicate a problem with
your system or lines; however, if this problem occurs persistently, contact your ESI Reseller for assistance.

Procedure(s)
• Check other phone functions. If you get dial tone when you lift the receiver and the
display is blank, the phone is defective.
• Make sure the Ethernet cable is plugged into the phone's NETWORK jack (and not the
PC port).
• If no phone functions operate, check the phone power supply. It should be plugged into
the phone and into an active AC outlet. If the display is still blank, the phone is defective.
• Contact your ESI Reseller if the phone is defective.
The phone is faulty. Contact your ESI Reseller.
The phone may be defective. Contact your Reseller.
Important: See page A.7 for instructions on connecting your phone.
• Check the cable between the phone and network access device (router, hub or switch).
This cable should be plugged into the NETWORK port on the bottom of the phone.
• Check that the link light for the port on router is illuminated. If this light is not lit check the
power supply connection for the router.
• Check the cable between the network access device and the modem. The WAN port on
a router should be plugged directly into the modem. If using a hub or switch, connect its
UPLINK port to the modem.
• Check your IP connection by using your PC to access a site on the Internet (after
accessing a Web page, press Ctrl R [for Refresh] to verify that your Web browser is
displaying fresh data).
•
Call the main office with a regular phone. Make sure the problem is not with the network
or IP connection at the main office.
The problem is probably with the connection between the phone and the IP PBX at the
main office. Ask your Network Administrator or ESI Reseller to evaluate your connection to
the main office.
