Small correction: I've just changed default TOS to be 0xb8, which is 
used by default by Cisco VoIP gateways.

I've also added new feature - "double RTP mode" (off by default), in 
this mode each incoming RTP packet whose size is below some pre-defined 
threshold (128 bytes) gets re-sent twice, which can improve QoS on lossy 
links. Threshold here is to disable this feature for non-LBR codecs. I 
like this feature from my SpeakFreely days. ;)
