Auto unwanted calls hit on my E Expressway

Dear all,

The unwanted automatic call hitting my E. Expressway from [email protected]/ * /.

How can I avoid or block it so that this appeal will stop hiting on my EXP_E.

Also suggest me if I want to block temporary external public VC call and how do I do this?

Thanking you.

It is a well known problem that has been raised repeatedly in recent years. Take a look at some of the threads in this thread: https://supportforums.cisco.com/discussion/12484441/hack-attack-vcs-express and this could be interesting:.

In short, you can block these types of calls by a combination of CPL and search rules, the corresponding section in the Administrator's guide is referenced in some of the threads.

You will not be able to stop these calls hit your E, but at least you can prevent these calls succeed, Yes, they will appear in the call log, but that's all.

If you want to block all external calls, you will need to put behind a firewall and do not allow something external.

Moreover, for calls SIP that you can prevent a large number of these calls by disabling SIP UDP, however, prevent the H.323 calls is not as simple as that.
