Application Development

Extended application development on top of Diameter Signalling Controller is done via the Python based Telephony Application Server (SVI-TAS).

Enables operators to interface to USSD, RADIUS, JSON, SQL, XML, SOAP, proprietary API’s etc.

The Telephony Application Server operates over clearly defined API's that present an abstracted version of the underlying Diameter, SIP, CAMEL, MAP etc signalling. It can be driven by either our python based client (SVI-TAC), or by operators 3rd party applications.

The SVI-TAS provides an extremely flexible platform on which operators can define, configure and launch new services.
