I do still have this issue, if someone calls me and I am already on a call - the new caller gets a message saying my phone is temporarily unavailable.
Can someone please help.
Have you ever had call waiting on the line?
Check page 11 of the phone guide for the Purple Zone

and see if it is switched on for your line?
Some past topics have mentioned this being switched on after the phone switchover (unknown to the customer). I think in those topics the next inbound caller to a busy line just got ringing tone rather than engaged. Turning off call waiting restored the engaged tone feature.
