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.
