programming an internet phone

[trashthing]

hi. i'm wondering how i would go about programming an internet phone. what i want the program to do is i would type in an IP and their computer will, i guess, ring and then we'll talk through the mic. i'm sick of AIM and ICQ, all of those programs.

you could use gnomemeeting (linux) or netmeeting (windoze)

[trashthing]

yea, but i need a project, so i thought i would make this program.

I work with this device often so maybe the protocols and codecs might help give you a start

Good luck.

Tell me when you have a runnable program. I wanna see it ;) .

Do you have any programming skills? If so, what languages?

Sounds like you'll need to study interfacing with the soundcard more than anything. Reading data from the mic and writing it out a socket, and reading data from a socket and putting it out to the speakers.

Not too tough (unless soundcards are ugly to deal with, which I know NOTHING about).

One simple way to approach this (which would have other uses) is to create a general-purpose program which, when run on both computers, will connect the standard input of one to the standard output of the other, and vice versa. Then on each computer, just do:

yourprogram > /dev/dsp < /dev/dsp

Obviously, this is a very rudimentary solution; you'd also want to include some kind of compression.

Can you also contact me once you have a worker?
