Nortel IP Phase 2 Phones != Leap Year

by

I thought I had seen it all until this morning.

While my PC showed the date as Friday February 29, 2008 my Nortel 1140E phone showed the date as March 1, 2008 (actual display reads “CS1000 03/01 8:14AM”).

The time/date on the Nortel Call Server was correct along with the time/date on the Nortel Signaling Servers. This was one of the weirdest issues I had ever seen. We opened a ticket with our voice reseller and waited for a response. It wasn’t too long before we recieved a reponse from the reseller along with an PDF document from Nortel.

It seems Nortel has released a bulletin describing a problem with Leap year that affects all Nortel IP Phase 2 phones. Unfortunately there’s no solution other than waiting for March 1, 2008 to actually come around (tomorrow).

Cheers!

ISC DHCP Server (Nortel VoIP)

by

I’ve received quite few messages from folks trying to setup and configure the ISC DHCP server that often comes bundled with all the major Linux distributions for Nortel Internet Telephony. Nortel has several “Technical Configuration Guides” that outline how to configure Microsoft’s DHCP Server but I don’t believe they ever discuss the ISC DHCP server.

I will admit that I really don’t use the ISC DHCP server these days. We’ve been using Lucent’s VitalQIP IP Management software to manage our internal BOOTP/DHCP/DNS/DDNS needs for the past 10 years.

However, since there was so much interest I decided to setup a lab (at home) with a i2002 phone and a server running CentOS v5.0. I installed dhcp-3.0.5-7.el5 via YUM and came up with a sample dhcpd.conf file that anyone should be able to modify to meet their specific needs.

   pool {
      range 192.168.0.50 192.168.0.100;
      deny members of "Nortel-i2004-A";
      deny members of "Nortel-221x-A";
   }

   # IP Address Pool for i2002/i2004/1120e/1140e/1150e
   pool {
      range 192.168.0.150 192.168.0.175;
      allow members of "Nortel-i2004-A";
      deny members of "Nortel-221x-A";
   }

   # IP Address Pool for 2210/2211
   pool {
      range 192.168.0.176 192.168.0.199;
      deny members of "Nortel-i2004-A";
      allow members of "Nortel-221x-A";
      }
 }
}

In the example above I setup two DHCP scopes; one for the standard hardwired Nortel Internet Telephones (Nortel-i2004-A) and another for the Nortel Wireless Phones (Nortel-221x-A). Hopefully this example should be fairly easy to follow just remember to edit all the site specific IP information.

Succession Internet Telephone Type

by

There are only a few phone types defined within the Succession Call Server for all Internet telephones.

The vast majority of Internet telephones are defined as either “i2002” or “i2004“. The 1150e is a special phone designed for Call Centers and is defined as an IPACD The Wireless LAN phones (2210/2211/2212) should be defined as “i2004“. Here’s a list of phones and how their associated TN should be defined;

Internet TelephoneTN Type
i2001i2001
i2002i2002
i2004i2004
i2007i2004
1110ei2001
1120ei2002
1140ei2004
1150eIPACD
2210i2004
2211i2004
2212i2004

It took me quite a few minutes to figure out how to define the 1150e the first time we purchased one a few months ago.

Cheers!

IP Phone Administration Password

by

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!

Reboot i2002/i2004

by

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.
