Hi Ugo,

The startup delay is probably caused by you ITSP or your VoIP device. Try 
reducing the size of your jitterbuffer (i think sipura calls this parameter 
"network latency").

Also make the VoIP rules tighter. Use something like
match udp
match packet size 0-500

Finally you could try to reduce the MTU. This may however bust some
