I have a customer that is having an issue with their MiCollab client.
When they fire it up, it works for ~1 minute to 90 seconds and then disconnects. They have to close it and reopen it to get connected again.
The problem started when they upgraded to new data switches.
I'm told there is not firewall in between them.
In the feedback report it seems to show that it timed out connecting to the server.
Mitel doesn't appear to have any suggestions so I'm wondering if anyone else has stumbled onto a similar problem.
Client version: 7_3_0_410

Ralph, does this happen when they get a call or just out of the blue?
-
Doesn't need to be on a call.
Note: Just to clarify, this isn't the softphone, it's the client that interfaces with the user's phone.

Assuming the client PC's are on a different subnet than the MiCollab server, what's handling the L3 routing? Maybe run Teleworker Network Analyzer on one of the PC's and see what that says.
-
I'm not sure how MiCollab works, but since you said after upgrading this happened, I assume that It would be either some NTP problem or some cache data remains on the clients that needs to be flushed!
-
I was thinking about a cache as well. But we uninstalled the client and reinstalled. - No change.

Sorry I've just noticed that.
It also could be related to broadcast storm on layer 2 network.
They should try to clear all mac address tables related to that vlan and force it to learn them again.
