FreePBX paging keeping Yealink phones offhook

Using the latest firmware(last 4 firmwares tested also) from Yealink on T26, any phone in a paging group will successfully go offhook, announce the page, but will stay off hook. You have to physically go to the phone and hit the speaker button to back onhook. We have 1 client that is wanting the paging and has 40 phones(only about 20 are in the paging group). Duplex is not enabable as this is an all-call ability “Frank, you have a call parked on 73”, etc. Any help would be greatly appreciated. v2.11
