I currently operate a DID (Direct Inward Dial) telephone number voicemail and call-forwarding service.
I currently use a legacy Centigram/Mitel platform and Asterisk.
The legacy platform sits in a data center and the Asterisk runs on cloud VPS.
I am wondering if Android can do these two functions better, as I do not have a client application that customers can download to manage their service.
I am at the beginning of this project and would like to talk with Android Telephony Developers.
