The CNMC published an analysis of two Ministry proposals (INF/DTSA/026/26 and INF/DTSA/027/26) requiring separate phone number ranges for customer service versus commercial calls. The CNMC endorsed requiring customer service through free numbers (800, 900), geographic prefixes, or short operator numbers, while commercial calls should use prefix 400. The CNMC recommended improvements including making customer service calls free on geographic numbers, making return calls to commercial numbers free, and extending the adaptation period from four to six months.
