Nortel IP Phones problems

[borceivanovski]

Hi all

I am having a problem with IP phones in the company.
I have 4 ip phones, 4 ip licences.

From time to time i get problem like restarting the ip phones automatically and connecting back to the server.

I am checking the logs, and i could not find anything regarding the phones or why they restart.

Any solutions?

Also another thing is that whenever i restart my VPN router the phones disconnect from the server as well, but they are not connected to the VPN, they are connected to the main switch and the router is disabled DHCP, and the phones are not configured to use DHCP, they use static ips.

Any help will be appreciated.

Also does anyone know where i can take training for BCM 200, 50? The company is expanding to several locations, and they need BCM 50 or BCM 200 installed on this locations, so why not me taking a training so i can do this.
If you know some training please tell me.
I am located in Toronto.

Thanks for all the help
Thanks

The IP Phones have a "heartbeat" mechanism with whatever (CS 1000, BCM,..) they are coneected to. If that "heartbeat" fails a number of times for any reason, then they restart to attempt to restore the connection.

Try Global Knowledge. I believe they have a center in Toronto.

Also consider Avaya IP office, as the BCM platform is going to be discontinued soon. You can still use the Nortel phones on the IP office, and you are supposed to be able to choose the Nortel interface for the phones as well, so to the end user it would appear they are on a BCM.

Personally, I would put a sniffer (packet capture) on the TLAN and review that with wireshark. We have found various causes for things by doing so.
The first thing to do is to make sure your phones have the newest firmware as well. If you are using a PoE switch it could be that device causing issues or if you are using PoE injecters (AC to DC plug-in to phone) than you could be having sporadic power issues in your building as well (brown-out anyone?) Anytime they lose power they will boot.

thanks to all for the replies.
First, gwebster, what should i do in order to see if that is the problem, and what is causing this problem?

Tman45, can you tell me what is the latest firmware, so i can check if it has it or not, but i dont think they have the latest firmware installed.

Can the firmware be the problem?

As Tman said, put a sniffer on the line and watch the packets coming from the call server to the phone. Those messages will point you to exactly where the problem is.

Firmware can be downloaded from inside of Element Manager.

Telus may also provide similar training.

They had a training location at Markham. Not sure if they moved to downtown Toronto.

If you are using a power brick for the phones, you might try to put one on a small UPS to see if the problem might be power interruptions. If that cures it, you can get UPS for all of them.

Any luck on this or more to post?

What model phone(s) do you have?

Are they on a separate VLAN?

How are you powering the phones? PoE switch? PoE injector? AC adapter?

Are the phones all going down at once, or different phones at different times? Are all phones affected or just one or two?

As for the VPN router, it sounds like your network isn't properly configured.
