I am in a similar situation.
I have an M900 base with two m65 phones, I have upgraded to version 450.13, and I have noticed some problems with rebooting on the terminals.
I have now updated to version 501 and reboots are very frequent.
what can I do ?
I've created a ticket for you and I'll reply in the ticket directly.
I think we have the same problem, we have now upgraded a Multicell System with 10 base and 70 handsets
Can you kindly help us too?
