Hello,

can you provide more details about what actually happens? High cpu? Dropped traffic? ...

Hi Guys,

I have built an SBC using kamailio with the dispatcher module and
rtpengine and when I run a sip test I find it struggles to go past
1000 calls at 20cps would really like some help on how to resolve
this. As I am very new to this I am stuggeling to work out where
to start from. I have found when running this sort of load the
debian box drops pings any ideas

Kind Regards
