I have DSL 128kbps internet connection

i have DSL 128kbps internet connection, which hardware needed to make calls to PSTN?

which PCI card / telephony board should i ask?

Please note:
1.Asterisk on server(Linux)
2.PCs with full duplex soundcard, microphone & speaker-Clients running on Windows 2000 professional

Please dont bother as i put in a separate topic :blush:

Digium X100P (Asterisk, Linux server)
TDM400P on clients (which also have Softphones like SJPhone)
As the softphones can also make PSTN calls

And X100P is for PSTN connectivity (1 line)

after going through Wilkemp’s suggested documents!

Please users any comments about my finding?
