I have 20 personal computers in LAN with full duplex soundcard, microphone(headset)
I will use this setup for making PC to PC phone calls(same as intercom in office)
in addition I have a Linux server, in which i will be installing asterisk
I have Internet Connection - DSL of speed 128kbps
I will be using asterisk for making calls to PSTN numbers(PC to Phone calls-like making outbound calls from each intercom, as well as receive calls at each PC installed with softphone)
so what are the additional hardware components needed?
i figured out,
Digium TDM01B (Asterisk, Linux server, for PSTN connectivity (1 line) )
And on clients, in all Personal Computers-running Windows 2000 professional (which have Softphones like SJPhone,As the softphones can also make PSTN calls)
please any comments about my finding and suggestions?
