No audio for 3 seconds on some calls
Hi All, I am running freeswitch 1.0.6 and some users have reported that they will be on a call and the audio will go silent for 3 seconds. This doesn't appear to be happening to all users. So far, I have done the following: - Internal and External profiles set <param name="rtp-autofix-timing" value="false" /> ( I was getting the RTP warning about ptime being 30 and all phones are set to 20ms) - Set the phone to use PCMA and made sure its PCMA through to the provider - We have installed a SIP Proxy at the other location so the voip phones all go via the SIP Proxy as we thought it might be a NAT issue. - Disabled VAD and CNG on the phone - The remote phones are connected via a DSL service but this appears to be rock solid and averages response times between 10ms and 40ms. I thought it might be something with VAD, is VAD disabled by default or should I add to the internal and external profiles <param name="vad" value="none"/ > Has anyone else come across something like this before? Maybe some other ways I can investigate what is going wrong? Any help would be much appreciated. Ash.
I think I may have solved my own problem... I am running on Ubuntu (I know its not recommended) and my kernel timer was set to 100hz. Running time_test 1000 1000 it would avg from 997 to 1300 when I kept running it. I have now set the kernel to be 1000hz and it now avg around 1008-1014 on multiple tests. Unfortunately its not one of those always happens issues so I will have to see how it goes. On 06/08/2010, at 6:38 PM, Ash wrote:

Hi Ash, Did you change your kernel to -preempt (10.04 Lucid Lynx) ? -- afshin On Fri, Aug 6, 2010 at 7:27 PM, Ash <ash@archerdrive.com> wrote:

Hi afshin, I changed to the linux-image-rt (real time preemption patch) and so far the calls have been good. A bulk of the calls will happen tomorrow so I will have more of and idea if it worked. Looking at it now its set to 1000HZ so I hope this solves the issue. Ash. On 08/08/2010, at 5:36 AM, afshin afzali wrote:
