Ghost Calls on Cisco Video Conference System
I had this question after viewing Cisco Access-List Ghost calls.
I get a lot of anonymous calls on my Cisco Video Conferencing System(SX20, SX80, C90) Is there a way to block these calls.
Currently, all I can do is to set the systems to DnD when I am in a VC Call. But when the VC is idle, we get about 50 - 100 anonymous calls per day.

My systems are all H.323 and they are all independent of each other. They are connected directly to an internet connection with a public IP address.
I dont have a voice gateway which I can use to configure any blocking.
Thanks for the suggestions anyway.

Using an ACL or firewall to block unwanted traffic would be the best option. Do you have a managed switch, router, or firewall between the conferencing system and the internet connection?

No I don't. The VC is directly connected to an internet connection and it is configured with a public IP address. This is because we have consultants company call from different parts of the world and having a public ip makes it easy for them to call.
I do have a Cisco VCS in my Data Center but even registering it on the VCS does not help with the spam calls.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You would have to either
A: Sounds like a Cisco CUCM, work with Telco on Blocking numbers if they are repeat numbers.
B: Work on your Voice Gateway and configure translates and such to block the numbers yourself. Not 100% but works. Better if your Gateway is H.323. MGCP less limited as it is controlled yb CUCM.
Hope this helps.
Thanks
