2. Describe the elements of a VoIP Dial Plan Design

3. Dial-Plan Components Fundamental VoIP network must have the following features: Local dial-peers to map phone numbers to a physical port Network dial-peers to map phone numbers to an IP address The ability to strip and add digits Number expansion

4. Dial Peer Types POTS or Local Dial Peers - means that the dial peer associates a physical voice port with a local telephone device. VoIP Dial Peers – On a packet voice network, these dial-peers point to specific devices

5. Module Objective 5 Configure Voice Interface Cards (VICs) to place VoIP Calls

6. A Voice Interface Card (VIC)

7. Various VIC Configurations

8. Voice Port Numbering Cisco IOS configuration commands identify voice ports in the form router-slot/voice-slot/VIC-port You can use the show voice port command to show the port numbers of the interface installed on your router.

9. VoIP Configuration Scenario

10. Some VoIP Configuration Commands dial-peer voice destination-pattern port session target

11. Step1 – Local Dial Peers To route a received voice call to the right destination, the router needs to know which telephone number belongs to each voice port If a call comes in for (408) 555-3737, the router needs to know that this telephone is connected to voice port 2/0/0 To hold this information, Cisco IOS software uses objects called dial peers

12. Step2 – Network (VoIP) Dial-Peers To route a call to the destination telephone over an IP network Commands used: destination-pattern session target

13. Example – West Router POTS Dial Peer config West(config)# dial-peer voice 401 pots West(config-dial-peer)# destination-pattern 14085553737 West(config-dial-peer)# port 2/0/0 West(config-dial-peer)# exit West(config)# dial-peer voice 402 pots West(config-dial-peer)# destination-pattern 14085554141 West(config-dial-peer)# port 2/0/1 West(config-dial-peer)# exit

14. West Router VoIP Dial-Peer West(config)# dial-peer voice 501 voip West(config-dial-peer)# destination-pattern 1919958.... West(config-dial-peer)# session target ipv4:192.168.11.3
