Definitely would appreciate some more info.

Are you looking to store and forward the audio, or do you want real-time audio?

Are your modems switched, or point-to-point?

Are your modems voice capable, or simply data modems?

Are you writing a program? Which language?

Do you want to broadcast to a single PC only, or one or more simultaneously?

Contact me off-list at spyke_at_erols.com.

Firstly thanks for replying to my query.
Answers to your qoestions.

Would like if in real-time audio if possible, but store and forward will do.

Dont know what to use, not familer with modems.

Modems are simply Data Modems.

Yes i will be writing program to send and play audio (Dont know How, but will try) Would be using VC++

Would require to broadcast to single PC normally but sometimes Simultaneouslt.

Please Help......
