Unlike US-based alternatives such as CallRail, Jet Interactive is Australian-owned and operated, meaning local support, local infrastructure, and a product roadmap shaped entirely by Australian market needs. Superior Reporting & Open APIs Where other platforms offer limited exports and rigid dashboards, Jet Interactive delivers reporting that goes as deep as your business demands.

Full SIP trunking support means Jet Interactive connects natively with your existing phone infrastructure, eliminating the need for costly rip-and-replace projects. Native integration with enterprise platforms including Genesys means your contact centre and call tracking data work together seamlessly — giving operations, sales, and marketing teams a unified view of every call. AI-Powered Conversation Intelligence Every call is automatically transcribed and summarised, so teams spend less time reviewing recordings and more time acting on insights. Sentiment analysis scores each call automatically, flagging at-risk leads, identifying high-performing interactions, and giving managers the visibility they need to coach effectively and respond quickly. Built for Marketing Agencies Jet Interactive gives agencies a single platform to manage call tracking across every client account. White-label reporting, multi-account dashboards, and granular attribution data make it easy to prove ROI and justify ad spend. See exactly which campaigns, keywords, and channels are driving phone calls — and bring that data to every client conversation with confidence. Australian-Owned, Australian-Supported Every Jet Interactive customer is supported by a team based in Australia.

Cloud private branch exchange (PBX) platforms, also known as virtual PBX, provide businesses with reliable and secure phone systems through a cloud server. PBX is a private telephone network that organizations use for internal communication and as a connection to external phone lines.

Cloud PBX platforms offer all the features and functionalities of traditional PBX hardware systems, with the infrastructure based entirely on the cloud. Cloud PBX platforms allow businesses to connect to their system from anywhere and on any device. It is great for remote and hybrid work environments since it requires minimal equipment and setup.

Cloud PBX is typically maintained and managed by a service provider, with implementation and administration done by the company’s IT team. Employees, especially those in customer service, real estate, healthcare, retail, or government industries, can use cloud PBX software.

Compared to a traditional landline system, cloud PBX offers businesses various advantages like minimized server maintenance, automated call routing, reduced equipment usage, lower overall maintenance costs, and easier setup.

Organizations are also drawn to cloud PBX due to its stability. Most platforms offer multiple data centers to avoid server malfunctions. Regular technological updates further ensure fast and seamless service. This provides businesses the peace of mind that their phone system will not lose connection easily, and business will continue as usual.

Cloud PBX is a newer and cost-effective option for companies due to its advantages over on-premise systems, such as its ability to scale, stability in connection, and easy manageability.

Another form of phone service software that works similarly to cloud PBX is voice over internet protocol (VoIP). [VoIP providers](https://www.g2.com/categories/voip) enable the transmission of voice over IP networks using various devices such as hardware phones, software clients, and service providers. It works independently or as part of a PBX system to provide enhanced communication features.

Whether a business uses cloud PBX or VoIP usually depends on the organization's size, technological infrastructure, and industry preferences. However, many businesses, particularly small enterprises, medium companies, and start-ups, opt for cloud PBX to streamline operations and reduce upfront costs.

To qualify for inclusion in the Cloud PBX category, a product must:

- Enable call forwarding, conference calling, voicemail, and automated attendant services
- Host phone infrastructure that works with just an internet connection
- Enable call monitoring with reporting and analytics capabilities
- Integrate with other communication platforms such as instant messaging, screen sharing, live chat, video conferencing, or SMS
