quality is fine. Note that a fast IP connection may or may not suffice. ^^^^^^^^^^^^^ <snip>
sending UDP packets over the Internet new problems arise. One packet ^^^^^^^^^^^ ^^^^^^^^ <snip>

I was going to just listen to the way this thread is going because I find it fascinating, but now that it has been spelled out, I must make a very important distinction between my idea and PGPFone, WebPhone, etc. -- These are Web-based programs designed to speak over very long distances for "free" (neglecting ISP charges, etc.), adding the extra functionality of encrypting your data along the way so sniffers, etc can't listen in on your conversation. My encryptophone(tm) :-) is purely a modem-modem protocol. This way, even at 14.4k you get all of your throughput. No TCP/IP overhead. No busy Net. No "Why won't my ISP hold a connection longer than TWO MINUTES!?!?". The idea I was tossing around was a simple modem program which takes digitized voice, encrypts it, pumps it through the phone line directly to the modem on the other side which undoes it all. (Yes, I know this is a simplified view.) I also know it may not be as useful as the web-based products, but I also know you don't have to worry about the aforementioned problems and neither party has to have a Net account. This eliminates some of the problems which have been sent to me. Of course, some of the problems still apply and must be addressed. I guess now's the time to admit that the first and foremost problem is that I have never programmed my soundcard... I appreciate the tips and pointers everyone has been giving me tremendously. Hopefully, this thread doesn't do a complete reversal, because I am storing all hints/suggestions/tips to be used when I can finally get this project going. (I'm stubborn. I need to at least try it, if for no other reason than to get the knowledge... :-) Thanks! PM

PGPfone works over POTS and IP. It was not originally designed to work over IP. The issues raised in my first post apply to modem/modem connections and IP based implementations. The issues raised in my second post apply to IP based implementations only (that's not quite true, but I don't want to go any deeper into it). --Lucky

There is a program out there called "nautilis" or something like that and it works just like the webphones but you need no web.
