[cisco-voip] H.323 Gateway Security - Prevent Unauthorized Usage

[Johan Bloemhard]

We have a 2801 with a H.323 gateway (PSTN).  I just came across a
student that was using IP Blue (VTGO) on their handheld and had
configured it using our H.323 gateway.  I imagine that he got the IP of
the H.323 gateway off of a phone.  Obviously he didn't have internal
dialing but could dial out with a problem.

 

How can we prevent this?  ACLs on the 2801?  How are other organizations
tackling this problem?

 

TIA
