We're trying to maximize security on our VOIP Gateway to avoid being victimized by long distance/international toll fraud. In efforts to address this concern, we're looking to somehow deploy a time based dial plan on our gateway (2821) which based on that it automatically shutdown outbound international dial peer for any calls made during off work hours (i.e 7pm- 7am including weekends):
dial-peer voice 119 pots
I understand this can be done inside Callmanager (we're running Callmanager 4.1(3)) as well but for extra security pre-caution we'd like to have it on our gateway preferably. Is there any way to accomplish this task on a 2821 VOIP Gateway?
