Correct answer should be C
CallingPartyTransformationMask
Enter a transformationmask value. Valid entriesincludethe digits 0 through9and the wildcardcharactersX, asterisk(*), and octothorpe(#). If this field isblankandtheprecedingfieldisnotchecked,nocallingpartytransformationtakesplace.
is it C is the right answer?
from documentation:
Cisco Unified Communications Manager uses connected line ID presentation
(COLP/COLR) as a supplementary service to allow or restrict the called party
phone number on a call-by-call basis.
A. Is wrong
B. There is no Called Party transformation Mask in SIP Route Pattern
D. This is only Allow/Restrict and does not change the Caller ID
My best guess is C. Calling Party Transformation Mask.

"Configure Calling Party Transformation Patterns
Use this procedure to transform the calling number. For example, you can configure a transformation pattern that replaces a caller's extension with the office's main number when calling the PSTN."
Correct Answer shd be D ..
Unified Communications Manager uses connected line ID presentation (COLP) as a supplementary service to provide the calling party with the connected party number. The SIP trunk level configuration takes precedence over the call-by-call configuration.
The question states "What field is configured to CHANGE the CALLER ID (Calling Partynumer) on a SIP Route Pattern?"
Whether SIP of SCCP or H323, in the basic call signaling they behave the same. Caller ID = Calling Party Number.
Connected Line ID Presentation of CLIP refers to ON or OFF, meaning it changes the way a CNG Party ID is displayed or not.
The question here is the WORD "CHANGE !!!!" and that is only doable with Route Patterns (Calling Party Number Mask) , Called Party Xformation Mask (CALLED PARTY but here we need CALLING Party) and finally the Calling Party Xformation Mask (CALLING PARTY + Modification)
I strongly believe the wording and question refers to Xformation Masks.
Lets not forget Xformation masks are NEW wheile CLIP or CLIR (Caller ID RESTRICTED the oposite of CLIP) has always been there since ISUP in SS7 or ISDN PRI.
C it is for me and in about 3 hours i have my exam and can be even more sure.
same here, keyword is >change<
Answer D is not fitting, because details explain >called party phone number<
where Caller ID is a phone feature that provides the name and number of a calling party
As long as we deal with manipulating calling, it is Answer C -> Calling Party Transformation Mask
Connected Line ID Presentation:
Unified Communications Manager uses connected line ID presentation (COLP/COLR)
as a supplementary service to allow or restrict the
called party phone number
B is correct. Is the only place to change the information. The Connected Line ID Presentation determine if the information is presented or not. But does not manipulate/change what the information it self is.
The answer is D.
The key is SIP Route Pattern and which field.
From Call Routing - SIP Route pattern add a new SIP Route pattern
The field to change is definitely Connected Line ID Presentation
D usage as described below should not be correct.
if we want to change dhe caller ID as the call is being forwarded, we should change it on the calling party transformation, so it C should be correct.
Connected Line ID Presentation:
Cisco Unified Communications Manager uses connected line ID presentation as a supplementary service to allow or restrict the called party phone number on a per-call basis. Choose one of the following options to allow or restrict the display of the connected party phone number on the calling party phone display for this translation pattern:
Default - This option does not change the connected line ID presentation.
Allowed - This option displays the connected party phone number.
Restricted - Cisco Unified Communications Manager blocks the display of the connected party phone number.
Note
If the incoming call goes through a translation or route pattern and the connected line ID presentation field is set to allowed or restricted, the system modifies the connected line presentation indicator with the translation or route pattern setting.
After reading more I do believe it is C Calling party transformation mask
