IP Phone Administration Password

Posted by Michael McNamara in VoiceOverIP on October 30, 2007

I can remember searching for hours trying to located these two “default” passwords for the i2007 and 1100E series IP phones. Hopefully this will make someones jobs a little easier.

In order to access the configuration menu of the Nortel i2007 IP phone while the phone is booting you’ll be challenged to enter the “Administration Password”. The following key sequence should work;

2, 6, 5, 6, 7, *, 7, 3, 8, OK

In order to access the configuration menu of the Nortel 1110/1120E/1140E/1150E IP phone while the phone is booting you’ll be challenged to enter the “Administration Password”. The following key sequence should work;

2, 6, 5, 6, 7, *, 7, 3, 8, Down

If the Nortel 1110/1120E/1140E/1150E IP phone is already running (connected to a Nortel Succession Call Server / Success Remote Gateway) you access the configuration by pressing the Services key twice and select the Network Configuration option.

Cheers!

Perl Scripting

Posted by Michael McNamara in Scripting on October 27, 2007

I really like using Perl because of the Net-SNMP Perl libraries that make it really easy to write code to interact with devices that support SNMP.

Hopefully everyone out there is backing up their network switch configurations in the unlikely event that if their hardware dies they only need to worry about replacing the hardware and not about re-configuring the entire switch.

Quite a few years back I wrote a Perl script that would send the proper SNMP commands to instruct a network switch to copy it’s configuration to a TFTP server. This script essentially became known as “switchtftpbackup.pl” It’s nothing fancy or pretty but it gets the job done.

I’ve posted this Perl script on my webiste under the Perl section.

I run this script from Cron one of our CentOS Linux servers at work every week. The same server also acts as a central TFTP server for the entire organization. I also run other scripts that then archive the weekly backups, in the event that I need to go to a backup that’s more than a week old.

I believe both Nortel’s Optivity NMS and Cisco’s Cisco Works both have options to backup switch configurations these days.

What are you using?

Cheers!

Reboot i2002/i2004

Posted by Michael McNamara in VoiceOverIP on October 27, 2007

A question that has often been asked by those working with these devices;

“How can you reboot/reset an i2002/i2004 without unplugging it?”

Well there is good news. You can reboot them without physically disconnecting the CAT 5e/6 cable (or the power supply if your not using the PoE functionality). The bad news is the key sequence is fairly complicated. The following key sequence will also work for all of Nortel’s Internet telephones (i2002, i2004, i2007, 1120e, 1140e, 1150e).

Here’s the key sequence you’ll need to follow;

  1. Mute key,
  2. Up Navigation key,
  3. Down Navigation key,
  4. Up Navigation key,
  5. Down Navigation key,
  6. Up Navigation key,
  7. Mute,
  8. 9,
  9. Goodbye key

Here’s a graphic that might make it a little easier to understand;


Once you strike those keys the i2002/i2004 Internet Telephone will reboot itself at which time you can reconfigure the phone by striking the four soft keys just below the display while the “Nortel Networks” logo displays on the LCD.

DHCP Options (VoIP) Part 2

Posted by Michael McNamara in VoiceOverIP on October 25, 2007

In a previous article we reviewed how to configure a Nortel Ethernet Routing Switch 5520 using ADAC/LLDP (802.1ab) so a Nortel Internet Telephone could discover the voice VLAN ID automatically without manually configuration of the phone.

If you don’t have a switch that supports ADAC/LLDP you can still utilize automatic VLAN assignment using DHCP. I’ve actually used this method (before Nortel supported LLDP) and it works well but can sometimes be difficult to troubleshoot.

You’ll need to configure DHCP option 191 (string) with the following syntax;

VLAN-A:vvvv.

Where: “VLAN-A” Option 191 begins with this string for all Nortel IP phones.
“vvvv” The VLAN ID for the voice VLAN in decimal
Here’s an example if I were trying to assign the phones with a voice VLAN of 31;

VLAN-A:31.

There must be a colon (:) seperating the VLAN-A from the VLAN ID. The string must also end in a period. It may be necessary, depending on your DHCP server, to enclose the enter string in quotation marks.

How does it actually work?
With the phone and DHCP server configured properly here’s how it will work.

  1. The phone will boot up and make a DHCP request for option 191 in the Default VLAN of the port connecting the phone.
  2. If the phone receives a response to it’s request it will issue a DHCP Release of the address it received in Step 1.
  3. The phone will make a second DHCP request in the VLAN that was returned in option 191. The phone will be requesting DHCP option 128 from the DHCP server, this will include the Call Server information. (Note: if you use a sniffer you will see that the DHCP packets will have an 802.1q header with the appropriate VLAN ID)
  4. The phone will connect to the Call Server specified in DHCP option 128 and will prompt the user for the Node ID and TN information.

With all that said we did leave out one very important piece of the pie… the network switch configuration. You’ll need to configure the VLAN and QoS settings manually depending on the switch vendor.

Cheers!
