Application Development

Get the most out of your existing infrastructure by utilising extended application development on top of the HTTP/2 Signalling Controller. Design, develop and launch new services rapidly using the flexible Squire Technologies SVI Open Gateway (SVI OGW), and leverage your existing infrastructure to boost returns on investment.

Interface with USSD, RADIUS, JSON, SQL, XML, SOAP, proprietary API’s etc, using our Python-based client or operator 3rd party applications. Open Gateway utilises clearly defined API’s to produce an abstract version of underlying signalling. (HTTP/2, Diameter, SIP, CAMEL, MAP, etc).

The flexible, service-driven SVI-OGW’s platform offers cost savings, new business opportunities, speed of deployment and many other benefits.
