Ringless voice mail broadcast service. Automatically delivers your pre-recorded voice message straight into consumers’ voicemail, without ringing the telephone. *** Replicate the voicecasting capabilities found here - [login to view URL] called voicecasting*** Voicelogic has a service that allows you to make a call that will go straight to voicemail without ringing the customer. I want to use vicidial voip service to carry the call and leave the message. Vicidial will need to place the "ringless call" to the voicemail number, and use the voicemail number to leave the recorded message. [login to view URL] also has this service. It appears the service calls the voicemail number and somehow leaves a message with the appropriate phone number.
