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 Hooman Fazaeli
