Lync --sbc --astrix

I trying to figure out a way to get lybnc client to make phone calls

It my believe need an sbc between it and trixbox

lync client 192.168.11.(DCHP)
lync server (fe and medation)

sbc internal
sbc external

trixbox(host by provider)

Tirxbox already in products … I just wnat add as little of configuration as possible so ti does not effect production


Anyone have steps on how to do this…

I want to use kamailio as the sbc

Thanks in advance
