Can I guess that they are using snom phones with firmware 7.1.30? I
encountered exactly that bug here, but only if I enabled "sendrpid" in
the sip.conf of the asterisk system. Downgrading to a more-stable
6.5.x snom firmware, or disabling "sendrpid" for all of the snom
devices fixed this in our case. (Roll on the next snom firmware
release!)

If not, then can I suggest that you provide more detail of equipment
involved - PCI cards, handsets etc etc?

Hope that helps,
Steve
