Just found asterisk and it might just be what I’m looking for. Could anyone please tell me if what I want is possible and, if yes, if there is a howto around that might get me started?
Our business has 3 ISDN-2 lines, I’d like to connect those lines to three ISDN cards in a dedicated server. This server should start acting as our phone central. What I want to be able to do is this:
- Use the 6 lines to the max on 4 phone numbers
Numbers A,B,C are on ISDN-2 line 1
Numbers D are on ISDN-2 line 2
If everything is busy on ISDN-2 line 1 it should be forwarded to another line.
- Connect our wireless Siemens Gigasets (we currently have 2 base stations, 1 DECT and 1 ISDN) to server
- Connect headsets to workstations and be able to forward existing calls to both the Gigaset phones as the workstations
- Program the server so that particular numbers are forwarded immediately (like our fax)
