Hi,
I'm having an issue with an SX20 device that keeps receiving nuisance h323 calls, no IP address is displayed and it just says "cisco". We have received over 100 of these calls. As a work around I have blocked all h323 on the firewall and only allowed a few IP's of known addresses that we use.
I tried to look in the logs of the SX20 to see if I could find the IP that was making the spam calls so I could block it but I couldn't find anything useful in there. Is there a better way around this as now I need to manually add an IP on the firewall every time they want to dial someone new?
Thanks
