Advanced Call Generator

Fixed Line and VoIP Test Call Generator

Fixed line continues to be an important revenue stream for communication service providers. In many cases now, CSPs are grouping PSTN, Mobile and Broadband products all together in one package as an attractive deal for subscribers. Businesses too rely on both fixed line and VoIP to carry out day to day activities calling both locally and internationally.

With many businesses around the globe changing to a permanent ‘work-from-home’ setting, the importance of assuring availability and the accuracy of metering and billing ‘at-home’ is on the rise. 

Assuring fixed line and VoIP is made possible through our Advanced Call Generators (ACG). They are built with  industry leading timing accuracy (+/- 100ms) like all our TCGs and are designed to work with our Osprey Suite of tools.

Our ACG units have been designed to independently measure exactly what the subscriber experiences including the ability to record in call audio for analysis of call quality. In the case of change assurance, ACG units can be used to verify the billing systems are calibrated as expected and voice services are being billed correctly, protecting your revenues and assuring your customers experience.
