| International freephone service |
 |
This Recommendation on the International Freephone Service (Blue Book - Melbourne, 1988) has been revised to bring it into alignment with current practice in the International Freephone Service, and to provide two additional optional ways of accessing the service:1) by dialling foreign domestic freephone numbers; and2) by dialling universal international freephone numbers, which use Recommendation E.164 country code 800 as a global service code, as defined in Recommendation E.169. |
