We are testing a couple of 8861 phones with a KEM attached on each, and the KEM keeps intermittently disconnecting on both phones. The phone shows the following message:
"The Key Expansion Module 1 has been disconnected"
Firmware version: sip88xx.10-2-1-16
I would like to know if anyone has experienced this issue and how got it resolved.
I'm trying to configure a CP-BEKEM, fot a 8851 phone, but can´t seem to find an example on how to do it. Can you help me out?
