Caller voice distorted 'donald duck or Dalek'
I am new to Voxalot, got reasonable understanding of IP telephony but terrible time to get it to work. Hope this is the right place to post.
However I have recently registered to test with voxalot because a friend is with voxalot. Registration successful but calling *600 does not work get half a ringtone and then dead. Calling my voxalot friend all appears fine, the call is set up and he sounds just great but my sound is only just understandable. I am testing with SJphone 1.65 on win2000, from private LAN via Netcomm NB5 modem/router connected to Exetel Added: Broadband link is 256/64 ie upload is 64 kb/s and my free sjphone does not have g729, however I was hoping it would try GSM to keep the bandwidt requirement down for uploading, hmmm? Can anyone enlighten me. Last edited by handy9; 04-14-2007 at 02:24 AM. Reason: Adding ADSL speed |

This is more than likely due to your upstream speed (64K).
You should most definitely try changing your SJPhone Codecs and remove the g711 ones from the list. *600 works from SJPhone so I am unsure what this problem could be.

Thank you Martin, I have come to look more and more in that direction. When I did the sjphone audio wizard test, in desparation, as my guru had installed the phone and said all was well. Well hard to question him??
Anyway when I carefully did the test I came to the conclusion that the Audio I was producing was terrible, seems I was lucky to do some improvement by switching off the AGC. Further I have come to the conclusion that if I could 'force' GSM codec I had to be able to do ok as test we have carried out from a 'dial-up' connection , the audio was impressive. Tomorrow this will again be tested. At the moment I have hit another problem with the sjphone, it will not respond to *600 echo check, well seems that WireShark sees lots of data but I don't hear anything, no ringing, no audio, just seems to run. My thinking is that if the echo test does not work then other problems will follow. Any ideas? |

My thinking too, dialed 600 and I get 1 ring, then silence.
First: I did find out how to enable GSM only so now only codec SJ Labs 6.10 codec running. 1.. sjlog indicates connection made, I can make an example copy available? 2.. WireShark [Ethereal] trace overview looks fine too, I get plenty of RTP packets but, now and then I get a packet that says Destination unreachable - Protocol unreachable I have a copy of the packet, but this is a bit too complex for me to decipher confidently. There is a mention of a protocol 17, have not found what that is yet. I have saved a txt file with copy of WireShark dump first 15 packets and corresponding sjlog, un request I will forward them but too big for thread I believe. As far as I can see connection is made, audio streaming according to WS but no audio on my system. The only Audio is the single call ring when connecting. ---- I have disconnected SJphone, not uninstalled and installed X-Lite3 which does the echo test perfectly. However here is another problem, will leave that til later. |

Oooops , hmmmm it seems that sjphone 1.65 is not the program to use with windows 2000. My Guru friend started up sjphone on his xp machine and noticed that I should not be running version 1.65. I have uninstalled and reverted back to a copy of version 1.60.289a and I am having success with echo test and registration.
Initially I had a really terrible voice/audio performance but I had luck finding the solution, I had installed Advanced help, great little addition to the phone, and via that I found that my audio driver buffer size which defaults to 20 ms is too short. I have tested 40, 50, 60 ms and all work fine I have also increased 'Driver output queue length' to 5, which is +1 on default. ------- New Problem: When trying to call another voxalot registered member, we are both in Australia, and I know he is on line and not engaged, I am consistently diverted instantly to his voicemail. The call connection seems perfect but sjlog does show that the 'owner' suddenly is us.voxalot.com?? Looking with WireShark I can confirm that at some stage "202.60.75.46 voxalot.com [Australia]" is replaced with"64.34.163.35 voxalot.com [usa]" for the rest of the call. [copy of file available on request]. I assume that we are not showing up as members on the us.voxalot server, a bit of guesswork? Any suggestions |
