Interface information

tyntec’s Global Number Portability resolves number portability by obtaining data directly from local number portability databases and live network information from across the globe.

The SIP (Session Initiation Protocol) interface is an application layer control (signalling) protocol. It is based on text (ASCII) and is a protocol similar to HTTP. It is based on UDP communication, which in general means that there is no guarantee from the protocol stack that packets arrive at their destination.

This is the overview of the workflow for querying portability information:


Here are a few specifics of the SIP protocol:

  • No username or password has to be transmitted.
  • The authentication is based on your IP.
  • There is no unique identifier (like the message ID used by other tyntec products). The identification of individual queries is based on the phone number queried, the IP the query came from and the query timestamp.
  • tyntec can customize the maximum time used before a result is given back (timeout parameter).  If tyntec does not get a response within this timeframe, you will get an error response.
