Moving Your Telephone; Troubleshooting - Nortel i2002 User Manual

Moving Your Telephone
Unlike some older telephone systems, there is nothing set­specific about the port your telephone is
plugged into. There is a non­changeable number stored inside the telephone when it is built, called the
MAC Address 3 ; Asterisk's chan_unistim uses this to identify your particular telephone set. You should
be able to move your telephone set to any location you like, as long as you can plug it into a port on the
same network. Some organizations will have separate voice and data networks, so be sure you plug into
the correct network port! Check with the administrator if in doubt.
If you need to pack up your i200x phone for shipping and decide to remove the base or "footstand", be
careful. Press the slider bar at the back of the phone, carefully spread the back away and, when it seems
almost off, push down so the two clips disengage (See Figure XXX). Oh, you weren't careful enough?
If you break it, the replacement part can be ordered as Nortel part number P0886045 (for the i2004).
If you need to pack up an 1120/1140, press the slider and gently "close" the footstand so it is parallel to
the front of the case. Be VERY careful when opening it after this; you have to press the release button
and the slider button at almost the same time, and gently unfold the base until the phone is at the angle
you want.

Troubleshooting

Phone completely dead
There are several possible causes:
Bad hardware; get your administrator to replace it.
Power and/or network cables not plugged in fully; make sure they're seated all the way in.
Network outage or bad cable; check with your administrator. Try another network cable or port
if available.
In any case, you can try rebooting your phone by removing the power source for ten seconds
and watching to see how it reboots.
Phone flashes red light then says "Server unreachable, starting in NN seconds",
over and over
The phone is not able to contact the Asterisk server. Either the server is down, or the network
cable isn't working or isn't plugged in.
You can hear the other person but they can't hear you, or vice versa
This is either bad hardware in your phone or, more likely, a configuration issue. Contact your
administrator.
"Sorry, this phone is not registered in unistim.cfg. MAC = xxxxxxxxxxxx"
3 Nothing to do with Macintosh computers, the MAC or Media Access Controller address is the "network hardware"
address; every Mac, PC, server, laptop, printer, etc., that is networkable is assigned one or more such address, and they
are supposed to be unique world­wide. This number is printed on the bottom of your telephone looking something like
MAC 00 12 34 56 78 9A BC – a "hexadecimal number" with numeric digits and letter A­F ­ and may show up in UNIX
or Linux (if you run a combined network) if you type "arp ­a" in a terminal window.
