Normalization of CallerID Number in MikoPBX

How to change the CallerID number format for incoming calls from the provider?

To normalize CallerID, you need to:

  1. Create a context with the provider name and suffix -incoming-custom
  2. Use functions to process the number:
  • REPLACE to remove characters
  • LEN to check number length
  • Substring to process parts of the number
  1. Check the application of rules through the verbose log of the incoming call
