The legal protective measures usually concern your contractual rights vis-à-vis the operator.
Whether you can appeal to a protective measure depends on each individual contract.
My company with limited liability has concluded one contract with operator A for fixed telephony.
As part of that contract I have been assigned 2 “fixed” numbers (for the shop).
My company has also concluded a mobile telephony contract with the same operator A, with 4 accompanying mobile numbers (for me and my staff).
The protective measures of the Telecom Act apply to the renewal or termination of each separate contract, even though the company has obtained 6 call numbers from the same operator (by way of 2 contracts).
