[OpenSBC] audio gets jittery and choppy and no rtp media on silence

[OpenSBC F. <ope...@op...>]

in recent times i have noticed that opensbc gets the audio jittery and choppy and rtp stream seems to stop on silence. Is there a way to define jitter buffer and keep a steady stream of rtp even on silence as i now mainly use it for encryption with freeswitch as the soft switch.

Perhaps this thread would help clear some stuffs.  http://www.opensourcesip.org:8080/clearspacex/message/8807#8807
With regard to producing silence on absence of RTP, that's not an SBC function but a switch or media gateway function.   If free-switch nor your gateways do not produce silence frames, why would you expect OpenSBC to do it?  So no, OSBC does not do silence-frames nor jitter-buffering.  OSSPhone and the IVR does because they are Media UAs.
