I would be nice to be able to create active voice messages: I call into dedicated VM and leave a message, then set time and recipient number. System will call the number at preset time and read the recorded message. Amount of recipients can be limited to 1 - 3 to avoid misuse (spamming).
This is known as call broadcasting.
I think we had a thread about this
before. I know I asked about it.
I think Asterisk has the ability, but
it is not part of the pbxes service.
