ASTERISK and UNISTIM Nortel 2002P2 Phones

Here's how I made a bunch of UNISTIM 2002P2s work with asterisk.  Specifically I used IncrediblePBX13 on CENTOS 6.7

The heart of this came from Mike "THE MAN!" MCNAMARA and Dale on his page.  They really provided me all the fundamental steps to get this to work.  I'm just collecting it here for my own record, and maybe to help someone out a little bit with my explanation of the process.

I did this on a bare metal build of CENTOS 6.7 using IncrediblePBX 13-12.2
UNISTIM drivers come with it and so far, works reasonably well.  I'm not sure if I would depend a large deployment on it, but its resurrected a box of phones that I had given up on.

So the assumption is that you have a pretty good understanding of the asterisk system.

So, in /etc/asterisk/unistim.conf is where you assign the phones you want to connect to your PBX.
I use FREEPBX for the GUI and created an extesnion (8860 in my example), but all that will do is assign a voicemailbox for your user really.  All the configs for the actual phone are stored in the file.

Here's my UNISTIM.CONF file:
______________________________________________________________
[general]
port=5000                ; UDP port
autoprovisioning=yes
qualify=yes
[8860]                                        ; extension of the device for reference
line => 8860                            ;the actual extension of the device
device=00148BF43A20            ; mac address of the phone (look on the back should be there)
maintext0="Asterisk"                ; default = "Welcome", 24 characters max. Shows on the LCD
callerid="First Last" <5558860> ;CLID that asterisk will pass
context=from-internal    ; context, default="default"
mailbox=8860         ; Specify the mailbox number. Used by Message Waiting Indication
linelabel="8860"     ; Softkey label for the next line=> entry, 9 char max.
rtp_port=10000       ; RTP port used by the phone, default = 10000. RTCP = rtp_port+1
rtp_method=3         ; If you don't have sound, you can try 1, 2 or 3, default = 0
status_method=0    ; If you don't see status text, try 1, default = 0
extension=line        ; Add an extension into the dialplan. Only valid in context specified previously.
                                ; none=don't add (default), ask=prompt user, line=use the line number

dateformat=1          ; 0 = month/day, 1 (default) = day/month
timeformat=1          ; 0 = 0:00am ; 1 (default) = 0h00, 2 = 0:00
contrast=5               ; define the contrast of the LCD. From 0 to 15. Default = 8
country=us              ; country (ccTLD) for dial tone frequency. See README, default = us

------------------------------------------------------------------------------

I saved this file.

Then I went to the phone, plugged it into the network.  Followed these basic config patterns.
(boot the phone, when you see the NORTEL text show, slide your fingers along the bottom row of buttons under the LCD from left to right)

EAP Enable? [0-N, 1-Y]: 0
DHCP? [0-N, 1-Y]: 1
Cached IP? [0-N, 1-Y]: 1
DHCP:0-Full,1-Partial: 1
S1 IP: xxx.xxx.xxx.xxx (Asterisk's Server IP Address) S1 PORT: 5000
S1 ACTION: 1
S1 RETRY COUNT: 10
S2 IP: xxx.xxx.xxx.xxx (Asterisk's Server IP Address)
S2 PORT: 5000
S2 ACTION: 1
S2 RETRY COUNT: 10
Cfg XAS? [0-No, 1-Yes]: 0
VOICE VLAN?[0-N, 1-Y]: 0
PC PORT?[0-OFF,1-ON]: 1
DATA VLAN? [0-N, 1-Y]: 0
PCUntagAll?0-No,1-Yes: 0
DUPLEX0-AUTO,1-FULL: 1
SPEED0-10Mb,1-100Mb: 1
GARP Ignore?[0-N, 1-Y]: 1

Saved the configuration file

Then I reloaded the config file in asterisk

Command line prompt asterisk -rx reload

The phone attempted to connect to the asterisk ip address, and presto.  worked first try.

The whole thing really worked, I had it working in less than 10 minutes.
