mitel ip handsets

[blackberry1980]

does anybody know handsets automatically go into failover state even if they are not resilient. The handsets show as "in service" in "ip telephones all" form but registration reason is failover instead of start. does anyone know why this is ?

thanks

ok I know why. Phones losing connectivity to controller and this is the last reason why the re-registering. Not sure why the phones are losing connectivity. data switches seem fine. Any ideas why phones would lose connections. data switch ports uptime doesnt show it going down.

If it's all phones, might be the connection to the switch. Unplug the patch cord to the phone system and the reconnect and make sure it's seated well. If it's just some phones do the same with them. I had a batch of phones that required firm pressure while inserting the patch cord for it to click in completely and connectivity problem went away.

Any logs in the layer 2's that might suggest something? Whats the ping time from phone to controller? Is it within specs? Layer 2's PoE or are the set powered locally?

When the sets lose connectivity there is generally a network reason for it. Even if as jonmyk suggests its cabling.

The single biggest problem with communications is the illusion that it has taken place.

Layer 2 switch provides POE, switchport stats show no errors and uptime of the port is good so the layer 1 seems fine. didnt check the ping delay. will check this.

Are phones on the same subnet as 3300? Have seen issues with problems with gateway assigned to the sets not being right giving them fits on connecting back to the 3300.

Phones in different departments reside on different vlans to the 3300, but they all use the same router configured with virtual interfaces for each vlan. No ICMP redirect is being used on the router.

Any on the same subnet as the 3300 and if so do they also experience the loss of communications with the 3300? The reason I ask is that there was another post a while ago with about the same symptoms and the problem proved to be the sets having something wrong with the gateway information if my recall is correct. I believe the sets "poll" the 3300 on a regular basis and if that gets miss directed the sets will not see the 3300. Just wondering if you have something like that.

Also as jonmyk states check or replace the network cable into the 3300.

you are correct loopylou, the phones do sanity checks and icmp redirect of the router was advertising a "better gateway" back to the 3300 this caused problems confusing the handsets, however in my instance there is no icmp redirect being used. I think that was an issue highlighted as a mitel tech bulltin. I dont have any ip sets in the same subnet as the 3300.
