Re: How to Blocking VoIP ( H.323) ?

["Alexei Roudnev" <alex () relcom net>]

Below, please:

  s/such/VoIP filtering/

and it will be true. It do not depends of alghoritm you are using.

Moreover, if you deploy such service, someone else can deploy VoIP which
uses https tunnel to it, and you will not have any chances than to block
total https traffic.

It (such thing) can be more  practical in corporate network (on gateway) or,
yep, in case if third force (gov.) requires it and you really want to comply
(not to show a compliance).

But I just dropped an idea, not the whole solution.
