Anthony, I actually thought about telling that to Sam, as it is the behaviour of Siemens DECT IP phones for instance. In the end, I think it would help to see a tshark trace of a such call.

I think you are talking about CN (payload 13) This is a rfc standard to send a packet every once in a while to prove it still works. if you negotiate CN in the sdp you would have it.

Sam, No there is no such thing as RTP keep-alive, AFAIK. But again, if you don't use VAD, there should be RTP all the time (except when on hold). So the first thing you should ask yourself is why is this RTP stream missing. Also you did not provide any information about the setup and the possible involvement of another equipement (provider ?). Be aware that if G729 is negotiated, it may use VAD by default if it was not disabled explicitly (that's the RFC).

There is no vad , is there something like rtp keep live after the increase of rtp timout . Yes the RTP timeout helps.

That'll do it.
VAD can mean no RTP is transmitted legitimately though, so be careful. Especially when on hold when the phone might stop sending anything (I see you've already increased that time).

I have this in the settings,
<param name="rtp-timeout-sec" value="3000"/> <param name="rtp-hold-timeout-sec" value="18000"/>
Any thing i need more regarding that ?

Hello,
We have a situation wherein we need to keep alive RTP ,is there any parameter to do that, because when someone is on long conversation and not talking fro brief duration the call disconnects .
