skype-out calls disconnect after 5 minute

[ajtiM]

My system: FreeBSD 7.2-RELEASE #0: Fri May  1 08:49:13 UTC 2009     
root at walker.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

Skype-out calls disconnect after about 5 minutes. I red that was problem with 
beta or pre release but looks like that is the problem here still. Version of 
Skype is 2.9.9.72.
Do I need to put kern.hz=100 in loader.conf, please?

Thanks in advace,
