The company I work at uses an Asterisk PBX, and I have been asked to find a way to add a ringless voicemail feature to our current system. I have searched through the documentation of Asterisk, and failed to find anything related to this. Has anyone else tried to do ringless voicemail through Asterisk, and if so, is there any documentation on this?
Thank you for your help.
(ringless voicemail is when a voicemail is placed in a phone number’s voicemail queue without ringing the phone. It is currently done by several commercial companies, such as GotVoice.)
