In Contact docType, there is no way to mention extension number. Ideally

  1. “Contact Phone” child table should have column for mentioning extension number.
  2. When a number is selected as primary phone number, it should be save in Phone data field with its extension number.

You have to add a new field called Extension (type: Data) in table. Then write a custom script for the Contact doctype. The script will check the Contact Phone table, find the primary phone, and include its extension in the Phone field of the Contact.
