Thanks for the tip.

Which Linux distro do you recommend (or have experience with) as the
load generator OS? I am a freebsd-ian and have little experience
with various Linux distros, so I need pro advise on one
that works very stably under high ISDN load (using Digium ISDN cards
and DAHDI 2.6+ drivers).

Best regards
