I know the 2211 has been Manufacture Discontinued for a couple of years. I believe the End of Life is August 2012. Thanks for the follow up!

In reply to Richard Springman.

Hi Richard,

I believe I’m running 097.071 on the few remaining 2211 handsets that we still have around so I can’t really comment. We’ve been migrating to the 6140 handsets for quite sometime now and they have been working really great.

Here’s the MD5SUM of the file on my TFTP server, I believe it’s 097.071 firmware.

Just as a quick note I believe the 2200 series handsets have been EoL and we’re currently having issues getting replacement batteries.

Thanks for the comment and the kind words!

Cheers!

Hi Michael,
We had been running 097.071 code on our 2211 handsets since a contractor set up our wireless network (Aruba APs, Aruba controller, Nortel 2245) about 3 years ago. While troubleshooting a WLAN VoIP issue recently, we upgraded the 2211 code to 097.072. We noticed right away that the phones would work fine for a while but then would either 1)freeze up 2) start buzzing and not stop or 3)display an error Assert:memory.c Ln 1068. Rebooting the handset would get it back to normal, but the errors would eventually happen again. We rolled the code back to 097.071 and the phones have been steady for the last 24 hours. Have you heard of the 097.072 code causing issues?
PS. Your blog has been a great source of information for me to learn about our own WLAN VoIP. Thanks!

Hi Ray,

That’s very interesting…

We are having issues with some of our older Motorola WS5000 (v2.x software) Wireless LAN Switches with Access Port 200 (802.11a/b) and the Nortel 6140 handsets. I just noticed last week that Nortel released firmware 115.019 for the 6120//6140 handsets so I’ll definitely need to give that a try. It hasn’t been a big issue since we are still using the Nortel 2211 handset and the vast majority of our wireless infrastructure is now Motorola RFS7000/WS5100 (v3.x software with Access Port 300 (802.11a/b/g) which doesn’t exhibit any issues with the 6140 handsets.

Thanks for sharing!

Michael,

Our facility also experienced issues with watchdog timeouts using the 6k series phones but the issue ended up being corrected by the latest phone firmware. We beat up our wireless equipment provider and Nortel (voice and data) and it came down to the phone. I am not sure specifically what was updated in the latest firmware but whatever was changed/added, it did the trick. It is like a new phone…huge difference all around.

Thanks,
Ray

Hi Michael,

Yes we’ve setup the Trapeze equipment for SVP support and we are using the 2245’s in the new clustermode.

Is it possible to pass me (on my email adress) the name(s) of the Nortel technician(s) who handled your case. This might help us to speed up things. Also Nortel Europe contacted me with the question to remove our conversation from your blog. That’s OK with me, you helped me anyway. If you want I can rewrite my first reaction without upsetting anyone.

Regards,
Wim.

Hi Wim,

I’ve removed your phone and email address from your comment, don’t want to contribute any more SPAM to the world. I don’t have any specific Nortel contacts for my specific problem. I opened a trouble ticket with Nortel and Motorola and worked through the process of getting the ticket escalated appropriately with both companies. The problem with Motorola was specific to changes they made in the AP code between their 2.x and 3.x software release so I’m not sure the same applies to your problem.

Have you configured the Trapez wireless switch equipment to support SVP as per the configuration recommendations put forth by Spectralink (now Polycom)?

Watchdog timeouts are a sure sign of loosing packets between the Nortel Succession Call Server and the wireless handset. The problem is locating where those packets are being lost, wired network or wireless network.

Thanks for the comment!
Good Luck!
