Hi, We have setup a new 3CX Server with a mix of Yealink Phones and Android Clients. We have about 12 mobile clients. All devices are of the same make and model with the latest 3CX client installed. We have noticed that 3 clients get a red dot in the extension overview. This happens when the device is locked. When we unlock, the device is set to the green dot and all functions work as expected. What is strange is that the other Android clients stay green even when in lock and wake-up as they should when called. We have our own push service account with google. I have noticed in the dailer log after rebooting the Qeuemanager that all the working Adroid Clients get a message like. " Update PUSH client for extn.***: Allowed, regid = **********" and then "PUSH Client for Extn.***:Registering" The Extensions with the issues do not appear in this list and appear not to get an update to the PUSH client. We have removed and recreated the extensions with all the settings as needed. Any help would be appreciated.
