I am also wondering what is the problem with xten and rtp proxy, because I didn't have any problems. Jan.

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!

Adrian, Do you have an Etheral trace trace of such a call (using G711)? I can decode it and produce an audio file for all to examine. This way we can get to the bottom of this.

The problem is that every few seconds there is a gap of half second in the audio stream (quality-wise the conversation is unacceptable) when using Xten softphone X-lite or X-PRO on either Win or Mac via RTPProxy. I can consistently reproduce this problem 100% on various systems and so do all my customers. For the sceptics, there is a movie with the problem presented (Quicktime is required to play the stream): http://download.dns-hosting.info/SERMediaProxy/ XtenProblemWithRTPProxy.mov and an audio extract: http://download.dns-hosting.info/SERMediaProxy/ XtenProblemWithRTPProxy.wav This is the problem solved in our media proxy.

Hi Adrian! I have just installed and tested it. Cool! My question: - Which port range is it using? Can this be configured? So for I found, that it uses at least port 35004... Thanx!

Hi Adrian! I looks I have already found the first bug. Pleas e be informed about the following issue: It seams to work only with one media (m=) line. Making a video session (which uses two media lines, one for audio, one for video streams), it only changes the first media port (or the media port for audio line). Is this a bug or did I forget something in the configuration?
