Extended application development on top of SVI-DSC product using the Python based (SVI-TAS) Telephony Application Server.
API
Enables operators to interface to USSD, RADIUS, JSON, SQL, XML, SOAP, proprietary API’s etc.

The SVI-TAS 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.
