[Serusers] Re: Xten-RTPProxy choppy audio

[Maxim Sobolev]

Probably you need to replace "we have solved" with "we don't observe", 
because to say that something is "solved" you probably should be able to 
describe what the solution is. Personally I am not convinced that there 
is actually a real problem with our RTP proxy (my own tests and Jan's 
information confirms that), it could be just equially likely be the 
problem with your setup (OS you are using, libraries, network etc). 
Therefore, I strongly suggest you to stop asserting that your version is 
better in this respect than original one unless you are able to tell 
where the difference is or to provide instructions on how to reliably 
reproduce the problem.

Thanks!
