Abstract:
In one embodiment, a network device generates a protection policy responsive to identifying undesired voice data traffic. The network device then distributes the generated protection policy along a call path used for transferring the undesired voice data traffic. The proxy may distribute the protection policy by inserting the protection policy in a call response or other message that traces the call path back to a calling endpoint.
