Hi refer to the documation that you provided from the link, I wonder to know what is the output / display of calling id on the ip phone shown?
The translation pattern and transformation pattern are two differnt patterns to change the number. For the translation pattern is used to match the number which is from the directory number (DN) whether it is matched to process the call routing.
The transformation pattern is used to change the telephone number whether calling or called number to different format. For the calling number, the correct redial outbound calling number is shown on the called party telephone.
For the called number, it is transform the internal to external number (inter-site calling or PSTN)
Question 1: why do wildcards prevent this feature from working?
For your q1, can you please provide the screen shoot of the called party display?
Step 5c states:
Choose Internal_Phones CSS from the Calling Search Space drop−down list.
Question 2: What is special about the Internal_Phones CSS? I have found I can use just about any exisitng CSS I have and the feature works.
The CSS is a calling search space. it is used to restrict the device from the device pool to make a call from particular number. Simplicity, it is a key(CSS) to unlock the destination (Partition). You need to create your own CSS for the internal phone. In the documentation, it is an example for you. If you do not configure the CSS, it does not make any different for the practice. However, it may not allow your phone to make a call for particular distination because of lack of key to unlock.
