Translation patterns are defined to provide a "translation of last resort." CallManager processes them just before it routes a call. After the translation pattern has modified the dialed digits, CallManager sends the transformed digits through digit analysis again.



The DN 0111 passes through the right-justified X wildcards. The result is that the CallManager prepends the 972555 to the 0111 and sends 9725550111 as the CLID information.



The predot digit discard instructions remove all dialed digits before the period.



You must apply the route filter to either a route pattern or a translation pattern for it to take effect. After you have applied it to a route pattern, you must select either Route This Pattern or Block This Pattern to define the allow or deny action.



The 11D@10D digit discard instruction takes an 11-digit long-distance number and converts it to a 10-digit number. This is typically used for toll-bypass purposes.



Applying a calling-party transformation mask of 8 causes all caller ID information to be replaced and become just the digit 8. To prefix an 8 using a transformation mask, wildcard digits (X) would be necessary.



Called-party transformation masks always transform the dialed-number information.



The order of application of digit translation applies the transformation mask before the prefix digits, causing the resulting caller ID to display as 5555123.



In this case, you have created a routing loop within the CallManager. The route pattern prefixes an 8 to the 4xxx dialed numbers and the translation pattern strips the 8 and returns the digits to the CallManager for processing. The call will loop ten times through the CallManager route plan and then return a fast busy signal.



Calling-party transformations change caller ID information, whereas called-party transformations change dialed-number information.
