Is it possible to implement in Asterisk a BT style call minder in an app or configuration.
For those that may not be familiar this is a nusiance or unsolicited call screaner, implemented either in an end device or at the exchange. The call is terminated before the users phone is rung (usually done by a DECT base unit for consumer products or centrally for a centrally provided service). The caller then hears and announcement which asks them to say their name and press hash. If they do not do this the call is ended. If they do the base unit or excange rings the users phone and advises them there is a call minder medicated call and plays a recording of the user’s opportunity to say their name. The user can then press a number to be connected with the reall call, send them to voicemail, or end the call. Additionally there are blacklists of callers who always are rejected or go to voicemail and whitelists of numbers which ring the users phone directly. Not done with BT call minder but nice to have would be a facility to put such black and white lists into groups and the action could depend on day of week time etc. E.g. accept from clients in the day time but send to voicemail out of hours, but, allow the wife stright through or vice versa.
