So I am trying to set up some new office phones with a Yeastar s20 PBX and Yealink T46s phones. I have a request that a single extension be put on 4 phones and that it be the same extension so that anyone with those 4 phones can pick up the call for that extension. I set up the extension to allow concurrent provisioning but it is not allowing me to put it on more then one phone, can I get some help with this thanks. Im not sure if I am doing something wrong or missing something.
