Phone Numbers

Why Choose Us?


If you want your incoming calls to be reachable via our system, you can either purchase new phone numbers or migrate your current one.

Phone numbers need to be purchased for the period of at least 12 months and the overall cost depends on the amount of phone numbers per block. A block of numbers is defined by consecutive numbers with the same prefix.

Note that you can always check your phone number subscription and its expiration date in your Voicetec account. Additionally, we'll send you an e-mail reminder 35 days before the expiration date, so you can decide if you are happy with our services and if you would like to continue using them.

We are very proud to say that all of our customers are not tied with oppressive contracts, but are convinced with quality and performance that we have to offer.

Important Information
  • Previous xDSL connections
    • For your xDSL connection, a number must remain with your xDSL provider. If operating an analog landline connection with xDSL, this number can only be ported if you no longer require xDSL in the future.
  • Note for existing supplementary services
    • If you obtain services that require a contract for a phone line, they will be automatically ended on the cancelation date. That may mean that additional infringement charges will be billed by your current provider. In order to avoid such additional costs, all additional agreements - by you yourself and respective limitations – must be terminated directly on the latest end date of the telephone connection with your previous providers. Your change of the telephone connection does not release the obligation to pay outstanding debts to your previous provider.
