[PLUG] VoIP on Linux notes.

[Henry J. Cobb]

For the demo on Sunday I showed how to use the X-lite softphone.

To connect to Asterisk servers on Linux.

The two types of Asterisk servers I connected to where Trixbox, an easy to
setup PBX system.

And Vicidial, a powerful dialer system.

I used iftop to show the bandwidth used in one call and talked about why
we use ULaw over SIP to connect to Asterisk servers that then combined
these calls into IAX trunks running G729.
