It will (optionally, see Step 2) prefix the calling number with 91 to make it easier for the internal user to call back the PSTN caller from IP phone Directory button (no need to manually add 91) PSTN 1010 408-555-30xx GW Dials: 1-408-555- 3010 303-555-6008

Digit Prefix and Stripping Prefix or strip dialed digits from a route or translation pattern for outbound calls – Part of Calling/Called Transformation settings. Transformation Masks Manipulate the dialed digits or calling party number – Part of Calling/Called Transformation settings. Translation Pattern When dialed digits match the translation pattern, Unified CM performs the translation first and then routes the call again. Make use of the Calling/Called Transformation settings for digit manipulation. Significant Digits Strip off digits received by Unified CM for incoming calls from a PSTN gateway or from a trunk.

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—4-23 Configuring Transformation Masks  Configured under Translation Pattern, Route Pattern, or Route List settings  Transformation masks configured at route list level have priority over those configured at route pattern level

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—4-25 Translation Patterns  Very powerful tool to manipulate dialed digits and calling party number for any type of call.  Can be used to either route or block certain patterns.  When the digits match the translation pattern, Cisco Unified Communications Manager does not route the call to an outside entity (e.g., a gateway); instead, it performs the translation first and then routes the call (to another translation pattern or to a route pattern).

All rights reserved.CIPT1 v6.0—4-30 Significant Digits  Instruct Cisco Unified Communications Manager to pay attention to only the least-significant N digits of the called number for incoming calls from PSTN or from another Cisco Unified Communications Manager cluster  Part of gateway and trunk configuration  Affects all incoming calls received by the gateway or trunk; not recommended for variable-length extension numbers

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—4-31 Configuring Significant Digits  Go to Gateway or Trunk Configuration > Call Routing Information – Inbound Calls  In the Significant Digits field, specify the last N digits of the called number that you want Cisco Unified Communications Manager to process for inbound calls received by the gateway or trunk

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—4-32 Significant Digits Example StepDescription 1PSTN phone dials 1-408-555-1010. PSTN switch routes the call to gateway. 2 PSTN gateway device configured with the following: – Significant Digits = 4 3 Cisco Unified Communications Manager will ignore all but the last 4 digits of the called number (1010). 4 Cisco Unified Communications Manager looks up 1010 and finds a registered phone with that directory number and presents the call to extension 1010.

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—4-38 Summary  In many call scenarios, it is required to manipulate the calling and called (dialed) string before routing the call.  Cisco Unified Communications Manager digit manipulation configuration main elements are: External Phone Number Mask, Digit Prefix and Stripping, Transformation Masks, Translation Pattern, and Significant Digits.  Cisco Unified Communications Manager External Phone Number Mask designates the fully qualified E.164 address for the user’s extension and is used to format Caller-ID information for outbound calls from the internal devices.

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—4-39 Summary (Cont.)  Digit Prefix prepends digits to a pattern, Digit Stripping strips digits from a pattern.  Transformation Masks modify either the calling number or the called number (dialed digits).  Translation Pattern can be used to either route or block certain patterns. When the digits match the translation pattern, Cisco Unified Communications Manager performs the translation first before routing the call to another translation pattern or to a route pattern.  Significant Digits instruct Cisco Unified Communications Manager to pay attention to only the least-significant N digits of the called number for incoming calls from PSTN or from another Cisco Unified Communications Manager cluster.
