I have already installed Trixbox on my server, the project now has changed to provide a bare minimum of functionality (I am dreaming big, but let's get it working and improve functionality later):
hook the machine up with [url removed, login to view]
connect the Sipura 3000 to the POTS line and configure it correctly
(I have done that before, should take an hour).
Provide the following functionality
System needs to distinguish between three DIDs (2 [url removed, login to view], one POTS line)
according to DID
voice announcement for POTS line: You have reached XYZ company, please wait while I connect your call
voice announcement for DIDs: You have reached ABC company, para Espanol, oprima el numero 2 en este momento.
IVR # 2 espere por favor, tratamos de conectar su llamada a la persona apropiada
IVR #1 please wait while we connect your call.
then call queue to extension 200 (my grandstream phone, alr eady connected) with the option to
send them to voicemail, just hang up.
Chanskype, no corporate license needed, since I am the only one answering the phone and
nobody should be able to call out anyway.
Predictive dialer, hylafax, all will come much later.
