J-series phones losing extension login

[Qzwsa]

Hi folks.

I've got a customer with an office spanning two floors. The main floor they expanded on to is all J100's of various models. Upstairs in the original space is all digital phones.

Periodically, random users will come to work in the morning and their J100 phone has logged itself out. Not the user, but the phone has lost its base extension assignment.

The last time, it was the big bosses phone so now there's a push to find the reason and not just log in the phones and continue with their day.

The IPO is running 11.0.4.7, Windows VMpro to match, and the J100s are running the latest 4.0.14 firmware.

Anyone else see this problem and/or know how to resolve it?

Thanks,
Qz

Not sure if this applies....it was on the Avaya support site.
Not sure what they mean by login servers. Unless its in an SCN with the IX client logging into a different system within the network.

1. Details
IP Office All editions and Platforms
Avaya Workplace
J100 Series phones

Problem Clarification
When a power user logs into Avaya Workplace App Desktop or mobile, they are logged out of their J series Deskphone

Cause
Mismatch of Login servers. Different servers were entered into J series, and IX Workplace
This caused the Extension to think it was hotdesking instead of logging in Simultaneous mode.
Solution
Ensure login servers on both devices match

2. I have had this happen to a customer on 11.1.2.3 and I upgraded them to 11.1.2.4 and haven't had any further reports of phones randomly logging off.
