We make a clear split for calls to premium numbers in the Netherlands, and calls to premium in other countries.
In the Netherlands we are connected with the COIN database and bill calls to premium (090x) numbers based on their actual up-to-date rates. You will receive a separate monthly invoice for calls to these numbers.
Calls to premium numbers in any other country, are billed using a flat rate specified on our online retail pricelist.
Alternatively, you may block calls to premium number ranges on your SIP accounts in the SIP Account configuration overview in our Voice Management portal.
