I have an end user who is experiencing a large number of unsolicited audio-only calls directed toward his videoconferencing units, and as a measure to prevent disruption of ongoing classes we were wanting to put a capset filter in place (using the “xConfiguration Experimental CapsetFilter” command) that would block audio-only calls. However, the syntax for the capset filter command is not documented in any of the guides available on the cisco.com website, and so I was wondering if you could provide that syntax.
We had success with blocking audio-only calls on his older MXP units in the menu under general. This option isn't there on the C-series And SX-series. It looks like applying the same filters to his C and SX series units should eliminate the issue.
To add to Patrick's comments, you say 'units', is the a gatekeeper or VCS involved? How are they protected from the public Internet - how are they deployed and what is the topology? I take it that the calls are IP and not via an ISDN Gateway or some such?
We too have seen a few of these "Cisco" calls but are trying to ensure that all customer have their unit is a secure VLAN behind a VCS. Yes, the gatekeeper gets hit, but we can control that a little easier.
He has an expressway (outside) control (inside) and TMS with a firewall between the expressway and control. I do believe it is on a secure VLAN. It's a university network and I wouldn't expect any less.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
