User contracts

If you are interested in the INA functionality offered by TELDAS, you should sign one of the following user contracts, but first we recommend you to consult our FAQ "How to become a User":

  • INA Benutzervertrag (German) or INA User Contract (English): This is the standard contract that provides you with both the possibility to query the central database of INA numbers for routing and billing purpose, as well as manage your INA numbers and tariffs (with a transaction fee for each such transaction). Note that for INA-TSPs wanting to port in/out INA numbers, you will need to sign also the ONP User contract, please consult our ONP Product section.
  • INA Filetransfer Benutzervertrag (German) or INA Filetransfer user contract (English version): This contract is sufficient if you only want to access to the file transfer functionality enabling you to download the call .
  • Note that the SLA INA is an integral part of the User Contract ONP (Appendix 5): This is a multilateral SLA valid among operators being part of the ONP process, to ensure that the agreed timing and process is followed by all parties, so that quality of service can be offered to the end customers. SLA penalties are to be charged among operators directly, TELDAS being not involved in the billing process itself. You can find out about the user SLA contacts here.
