Hello, with Ver. 20 Update 6 (rel build 724).
I try to register on a new user a yealink t43u but ther is error "MAC ADDRESS ALREADY IN USE" that stop me.

The ip-phone was of a user that have an other phone. And at the time, the following phone was removed from the IP phones section. How do I resolve this error?

Hi,

If you search this MAC in phones or users, it does not come up? Is it a Router phone?

It isn't in the phone list.

This means the MAC still assigned in the IP Phone tab of one of your users

1. you have to check them all and click on their phone in the drop down list because maybe you've added two phones and its not immediately visible.


2. and check the Voice & Chat page, if you added any DECT/FXS devices using this MAC you will get the same error message again.

Ok,i'll check, but why it is not in phone list?

Phone list only shows phones that are currently registered. If you unplug or reset a phone it will disappear from there within a minute.

A checkbox or dropdown for "show unregistered" or "view all" or similar would be handy here. And probably head off many of these questions.
