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).

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).

because when someone is on long conversation and not talking fro brief duration the call
disconnects .
