A list of country codes. An incoming number's country code is stripped before performing a Number Portability database lookup since the database lookup requires national significant numbers.
This is the key attribute of the CscfNumPortabilityCountryCodeList class. One instance of the CscfNumPortabilityCountryCodeList with the key cscfNumPortabilityCountryCodeListKey=0 is created at startup. This instance cannot be deleted. No other instances can be created of this class.
