[Freeswitch-users] No audio for 3 seconds on some calls

[Ash]

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.
