7. 7 New ECS Hot Standby Alternate Gatekeeper for redundancy New ECS Pro Hierarchical structure Enhanced Dial Plan for simplified dialing Wild-Card Digit Manipulation 123* 8* ECS receives the number 12345678 and knows to change it to 845678 123* * ECS receives the number 12345678 and changes it to 45678 DNS Support- ECS can contact preconfigured DNS server and receive a listof gatekeepers relevant to the domain queried New ENC Network Configurator For Easy Installation and Setups Introduces new ECS onto the network without having to change the configuration of other Gatekeepers All ECS can utilize ENC for convenient updates using ENC database ECS V2 Enhanced Gatekeeper

8. 8 ECS Network Configurator - ENC Part of the ECS Pro package Central point for Gatekeepers topology configuration Hierarchal ECS Gatekeepers structure Strip/Do not strip zone prefix rules Parent Filter – avoid unnecessary network traffic Supports country and international level dial plans Full integration with the PSTN and ISDN networks (using the RADVISION gw-P20)

10. 10 Call Fallback For IP Calls If the destination is not found: Send to auto attendant (alternate H.323 address) OR Send out the local GW or to a specific service Call Realization! A destination will be searched for…

11. 11 H.235 v2 Security Endpoint Support Authentication and Integrity verification Verifies that the sender and receiver of a message are, in fact, who they say they are Verifies that data has not been altered in an unauthorized manner Whenever an endpoint sends a message to the Gatekeeper, the endpoint encrypts the message using the password. The Gatekeeper receiving the message authenticates the message using the same password. If one of the parties does not have the correct password, the authentication fails and the transaction is rejected.

12. 12 SNMP Traps NMS needs Alerts and Alarms Interfacing with other servers ECS Going up ECS Going down Call error License error Registrations, Calls, BW Capacity Alerting the Administrato r!!

13. 13 Alternate Gatekeepers allow the endpoint to register and call the destination when the original GK goes down. This is accomplished with a Hot standby GK that receives al information from the operating GK. It is knows if the operating GK goes down, and automatically assumes the GK's IP and full operation. When the original GK goes up, it then becomes the slave of the now operating GK. Alternate Gatekeeper Solutions Built in Mirroring Information to Hot Standby Slave-Master Routine
