What isn't OpenSS7?

Description: OpenSS7 Frequently Asked Questions #3.

OpenSS7 has no relation to these other things which come up on a search for SS7:

• It is not a motherboard.
• It is not a health care system.
• It is not a database interface.

OpenSS7 does provide a largely complete ISUP or TCAP stack. It is a platform upon which you can build a Softswitch (but it is not one, yet). It is a platform upon which you can build TCAP applications (INAP, MAP), but it does not yet provide these applications, only the stack components.

OpenSS7 isn't MAP, it isn't AIN, and it isn't an application. Consider it similar to an IP stack with TCP and UDP. You can open an MTP, SCCP, ISUP or TCAP stream and communicate to the outside world using SS7, you can even bind to an ISUP trunk or TCAP subsystem, but what you might want to do with that stream is a matter for the application.

There are a number of opensource projects which are concerned with the application level using SS7.
