Voicemail issue and caller id announce

I have 4 Sangoma S500 setup the same using the same template.
One of extensions rings once then goes to voicemail. It’s not on DND and calls can be made out.
Another extension announces caller id when a call is picked up from it.

The other 2 phones on this template work fine. I have 18 other Sangoma S500 and 4 S300 on this PBXact install and other templates not having any issues like this.

Is there something simple I may have overlooked?
