Destination in Use Notification

[jholcombe]

I didn't say the previous server could do this, I said the previous phone system did this. The previous phone system consisted of a Nortel BCM 450 with Nortel phones. Can the software (in this case, 3CX) tell a phone to display something (for example, "On a call" to indicate that the destination is in use? Or is this something I can configure in the phones web interface for users who need this functionality? Thank you!
