Benefits of call management APIs

VoLTE is just the first step on a journey to API-ness

More than 130 operators in 65 countries have launched VoLTE voice services. And for good reasons. VoLTE delivers better voice quality, fast call set-up, reduced costs for operators through network simplification and higher spectral efficiency that makes better use of valuable spectrum.

And now they’re discovering how it can become a powerful new source of revenue. Call Management Application Management Interfaces (APIs) enable VoLTE to evolve from a mere standalone service into a set of sellable and sharable features that can be embedded into any mobile application, web application or device.

These APIs use a wide range of advanced features - artificial intelligence (AI), big data analytics, speech recognition, voice-based messaging and Internet of Things (IoT) analytics can all be used to enrich the communication experience, whether voice or video. APIs offer a huge degree of flexibility to call processing and can accept information from the network and be given direct access to and even control of calls.

New services, quickly deployed

For an operator, Call Management APIs make it easy to introduce new services, cutting the time to bring them to market. Built into Nokia Telecom Application Server (TAS), the APIs employ easy-to-use software to create applications for the web. You don’t need training or detailed telecommunication knowledge, just regular web development skills.

Pre-integrated partner applications allow the operator to retail new services very quickly. Major operators are already evolving VoLTE to take advantage of these capabilities. One such is China Telecom, which launched a new service that allows riders and drivers to keep their phone numbers private when using the Didi Taxi service. The operator has added over-the-top (OTT) partners in other industries.

In another example, a leading North American Communications Service Provider (CSP) worked with Nokia to develop and introduce an application service which automatically detects phone numbers from unknown parties, including spam, fraudulent, or nuisance calls, then labels them so the user has the option to block them in the future, enhancing the mobile experience

No limits to innovation

The services that can be built are only limited by developers’ imaginations. Those developed by Nokia partners include Call Protector, which blocks nuisance calls and requests anonymous or unknown callers to record their identity.

Another is Click-to-call-me, which allows one-touch calling on an enterprise’s website or a subscriber’s email signature.

They further allow an operator to offer advantages to users that go beyond anything that rivals can provide. For example, an operator could build a ‘secret garden’ of features giving it an edge over other service providers.

APIs are a powerful way of generating new sources of income. An operator could maximize the value of the IMS core by creating and launching new carrier branded services. It could expand into wholesale markets by partnering with app developers and explore new business models or extend its reach to new verticals and connected objects.

VoLTE is a great offering, but with Call Management APIs, it’s just the first step to a whole new world of services.
