I just converted over to 3CX and have Aastra phones that are legacy type of phones that are supported. However the calling list button on the phones are now not showing any incoming calls to the phone. In researching it says the Provider needs to set it up, thus being me. I can find anything in the webgui. In contacting Aastra they said it has to be provisioned by the provider. When they said through 3cx. However none of the Aastra phone will automatically provision and need to manually provision and configure.
