The V9 PBX supports provisioning for Android phones, but due to some last minute problems with the Android 3CXPhone provisioning it had to be disabled in the 3CXPhone in our internal builds.
The current released version of the 3CXPhone supports provisioning ( I might be wrong, we may of have replaced it with a Version without Provisioning Enabled ) but it takes a long time to provision. ( This is the issue )
I'll give you a shout when this is fixed. Though it's gonna take a while
