a friend of mine recently told me he’s looking for a PBX that catches incoming calls and presents the caller a menu where he can choose by typing numbers which person he wants to talk to.
The caller than should be forwarded according to his choice to one of two mobil phones.
Additionally he wanted if the called does not choose the call to be forwarded to a default mobil, and if this is busy he wants the PBX to ty the other one automatically.
I’d like to ask if this (voice menu, conditional forwarding, “external line busy” detection followed by alternative routing) is possible using Asteriks, plus I’d like to ask if VoIP (using DSL) instead or in addition to a second ISDN account for outgoing calls be be integrated?
Thanks in advance
