If you want a call from the number 422033272020 to display as +44272020, what pattern is used for "Inbound CID Reformatting"?

The correct choice is based on understanding how inbound caller ID reformatting works in 3CX. In this scenario, the goal is to transform the incoming number "422033272020" into the format "+44272020".

The "Inbound CID Reformatting" pattern allows specific sections of the incoming number to be captured and restructured. The selected pattern, which includes "44(..)(..)(.*)", is effective because:

• "44" matches the international dialing code for the UK, which is required as part of the reformatted number.

• The two sets of "(..)" capture the next two digits after "44". This means the second part of "422033272020" (which is "72") is captured.

• The "(.*)" captures everything that follows; in this case, it captures "020" from the original number.

Together, this pattern effectively captures the necessary components of the incoming caller ID and reformats it correctly as "+44272020".

In contrast, the other options do not encompass the needed elements to achieve the desired format. For example, some patterns do not include the necessary parts of the number sequence or miss capturing parts of the incoming caller ID that need to be included in the final result
