Someone gave me a ballpark ofv128kb upload per channel. I have no idea how accurate that is. Download is usually faster on most connections so upload is the bottleneck.
Any optimization sounds like compression,and you can only do whatbtheother end supports.

Thanks for your prompt response. Ive searched alot to find out best solution . I came up with RTP compression as you said ,I found www.rohc.net its an library for compressing RTP . Since Im not a programmer so having trouble to implement it in linux to test. Any guideline would be appreciated or linux QOS package with ROCH implemention. Looking forward for your kind response.

What has the other guy got? That's your limitation. It is the same with things like ethernet bridging. If the other end does not support it, it is no use.

EDIT: rohc is HEADER compression. That is like scrambling the address on the envelope - a great way to get your mail delivered - not! :-). The header is a small bit at the beginning of the packets. That idea is dead in the water, because _no_ router wants to have to waste time uncompressing headers. It's not one that will fly in the big bad world.

You want an accepted way of compressing the voip data. The best way is to reduce sampling speed. You can slow to about 8K samples/sec which is about the minimum for speech. That is 64K per second for one channel at best.

Set the sampling speed on your soundcard; that's what we are talking about. Also send the most space efficient format. No idea how to implement. Just nebulous theory. Requires a bit of work on your part

There are so many website which provides this services. I am using telepacket optimizer, my one friend is using same. So it would be great for you to ask to service providers.
Thank you.

Thank you.
Please don't re-open old threads...this one was closed for TWO YEARS now. And if you're going to re-open it, please abide by the LQ Rules and post something relevant...more than telling someone to look at "many website" for something.
