Cisco Small Business Webinar for Partners - Technical Track

1. Cisco Small Business Webinar for Partners - Technical Track Dial Plans for Small Business Translation Rules, Dial Peers, and COR Skyler Spence skspence@cisco.com Support Engineer

2. Dial Plan Configuration • New S Business Webinar Series for Partners • When making CLI configuration changes, always consult the CCA Out of Band configuration guide found at http://www.cisco.com/en/US/docs/net_mgmt/cisco_configuration_assistant/version1_8/out_of_band_reference/cca_v18_oob_config_guidelines.pdf • This presentation may be found at www.cisco.com/go/smallbizsupport • This presentation uses CCA version 1.8 and IOS version 12.4(11) XW9 • This presentation will cover the configuration of dial plans on the UC500 platform.

3. An Overview of Call Flow

4. Dial Peers • A Dial Peer is matched whenever a call comes into or is placed from the UC500. Therefore each call involves both an inbound and an outbound Dial Peer. • Dial Peers are matched based upon either the calling or called number or by port number when this information is not available.

5. Types of Dial Peers • There are two types of Dial Peers to configure on the UC500, POTS Dial Peers used to interact with traditional PBX systems, and VoIP Dial Peers used to send calls across the network. • The syntax for defining a Dial Peer is dial-peer voicenumber {pots | voip} • POTS Dial Peers match calls to voice ports while VoIP Dial Peers match calls to session targets which can be an IP address or DNS hostname. • For more information about Dial Peer configuration and uses, please refer to the document at http://www.cisco.com/en/US/docs/ios/voice/dialpeer/configuration/guide/vd_dp_feat_cfg.html#wp1067010

6. Inbound Dial Peers Matching

7. Direct Inward Dialing • When configuring inbound Dial Peers on a system using PRI/BRI services, it is important to configure the direct-inward-dial command. This command, available only on POTS Dial Peers, makes sure that the called number presented in the call setup information is used to match an outbound Dial Peer. • If DID is not enabled on the matching inbound Dial Peer, a dial-tone will be presented to the caller enabling them to input a new dial string to call where they wish. • For more information, please refer to http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00801142f8.shtml

8. Outbound Dial Peers Matching • In order to match outbound dial peers, the UC500 uses the dial peer destination-pattern called_numbercommand • On POTS dial peers, the port command is then used to forward the call • On VoIP dial peers, the session target command is then used to forward the call • The following figure shows the relationship between destination-pattern and session target

9. Destination Pattern • When the router attempts to match an outbound Dial Peer, it compares the called number to the destination-pattern configured. This is in contrast to matching inbound dial peers when the calling number is compared to the destination-pattern. • The destination-pattern can be either a complete telephone number or a partial telephone number with wildcard digits. In addition to the characters 0-9, #, and * the following symbols are defined for destination patterns* *Wildcards may also be used to match inbound dial peers.

10. Notes on POTS Destination Patterns • VoIP dial peers transmit all digits in the called number by default; however, POTS dial peers remove, or strip, any outbound digits that explicitly match the destination-pattern. • To disable this behavior, you can use the no digit-strip dial peer configuration command. • The prefix digit command adds a string of digits and pauses (represented by ‘,’) to the beginning of the string transmitted by a POTS dial peer. • The forward-digits command can be used to forward a fixed number of dialed digits, or all dialed digits, regardless of the number of digits that explicitly match the destination pattern. The forward-digits 4 command tells the router to forward the last four digits in the dialed string. The forward-digits all command instructs the router to forward the full dialed string.

11. Translation Rules &Translation Profiles • Translation Rules provide a simple and powerful method for adding, subtracting, and splicing numbers • The basic format is:voice translation-rule <tag(1-2147483647)> rule <tag(1-15)> /match pattern/ /replacement pattern/Note: / -- / delimits the whole number • This example replaces the first occurrence of the number "123" with "456“.voice translation-rule 1rule 1 /123/ /456/ • There are multiple special characters that allow patterns to match a wide range of dial strings. • Translation Rules can be tested using the command test voice translation-rule name-tag input-number

12. Translation Rules & Translation Profiles • This table defines wildcard and wildcard combinations

13. Translation Rules & Translation Profiles • Once a Translation Rule is made, it can be put into a Translation Profile where it is applied to the called, calling, or redirect number or the redirect target. • The syntax for a Translation Profile is:voice translation-profile <name>translate <target> <rule tag> • The Translation Profile is then applied to a Dial Peer. • More information on Translation Rules can be found at http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a0080325e8e.shtmlandhttp://www.cisco.com/en/US/tech/tk652/tk90/technologies_configuration_example09186a0080094681.shtml

14. Class of Restrictions (COR) Lists • COR Lists are used to control which Dial Peers an individual user may access. To control who can dial certain patterns, international numbers for example, you can apply a COR list to the Dial Peer that matches that destination-pattern. • To create and apply COR lists, follow these steps • Note that any ephone-dn without a COR list applied is given full privileges.
