This match is made based on the called number, calling number, or voice port. After matching an inbound Dial Peer, translation rules or profiles configured on that Dial Peer are applied. Finally an outbound Dial Peer is matched based on the called number and COR list configurations.

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. © 2007 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 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 voice number {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/g uide/vd_dp_feat_cfg.html#wp1067010 http://www.cisco.com/en/US/docs/ios/voice/dialpeer/configuration/g uide/vd_dp_feat_cfg.html#wp1067010

This is not the recommended method. Calling # port This dial peer command defines the POTS voice port through which calls to this dial peer are placed. (POTS Dial Peers only) Voice Port

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_note091 86a00801142f8.shtml http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note091 86a00801142f8.shtml

All rights reserved.Cisco ConfidentialPresentation_ID 8 Outbound Dial Peers Matching  In order to match outbound dial peers, the UC500 uses the dial peer destination-pattern called_number command  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. © 2007 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 9 Destination Pattern SymbolDescription.Indicates a single-digit placeholder. [ ]Indicates a range of digits. A consecutive range is indicated with a hyphen (-) a nonconsecutive range is indicated with a comma (,). Hyphens and commas can be used in combination; for example, [5-7,9] %Indicates that the preceding digit occurred zero or more times. This functions the same as the "*" used in regular expression. TIndicates the interdigit timeout. Should be used carefully, most often for international dialing plans. 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.

All rights reserved.Cisco ConfidentialPresentation_ID 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.

[0-9]Any range or sequence of characters *Modifier-match none or more occurrences +Modifier-match one or more occurrences ?Modifier-match none or one occurrence (Ctrl+V+?).*Any digit followed by none or more ocurrences. This is effectively anything, including null..+Any digit followed by one or more ocurrences. This is effectively anything, except null. ^$Begins with and Ends at. Together indicates null.

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. 1. Configure dial-peer cor custom and assign a meaningful name that specifies the way CORs apply to dial-peers. 2. Create the actual lists of the restrictions that apply to the dial-peer. 3. Create dial-peers and specify the COR list to be used. 4. Apply the COR list to the individual Ephone-dns.
