Hello folks !
I need to put an Asterisk server between our main ISDN Lines (4 BRI with 8 simul. calls) and our actual PBX, as we need to filter phone calls (who can call us, at what time he can call us, etc.) without replacing our actual infrastructure.
Someone could think that it would be better to replace PBX; this filtering solution should be considered a test and it should be removed shortly (1 month or 2), so we can’t replace anything inside.
What hardware could I need to make a bridge between my ISDN lines and actual PBX using Asterisk?
