Thanks for your response.
I think the box is good the OS ubuntu 64bit is ok 10.04 (little bit old but still).
Interrupts are also fine traffic is on eth1 ?
Can load balancing the RTP/SIP over more eth interfaces give better performance. ?
The key point is that the box is not very busy but I introduce Delay in the RTP more than 100ms on 20% of the packets
I am very impressed with this box flexibily and feature rich. If I can upscale the RTP sessions and can prove that it is the hardware/Os that is causing the limits I can look for a solution for that.

you could do with more than 2 cpu, the more cores the better you will do.
For similar prices you could find a 8 or 12 core box.
The 3 most important things in a FS server are, as many CPU cores as
possible, as much ram as possible, the best possible CPU with shared
bus to RAM and CPU.
