Voice is how we naturally communicate and can often be more appropriate than SMS text, email, chat or other forms of written or visual communication.


Voice Gateway is about enabling interaction through voice; from inbound and outbound call termination, to bridging between voice and other communication channels and applications. With Voice Gateway you can easily and effectively integrate voice into your systems.


The Melrose Labs Voice API provides access to the services that are part of the Voice Gateway. As a minimum, all the services are accessible using a REST-compliant HTTPS interface. The Melrose Labs Voice API commenced roll-out Q2 2019, starting with the Text-to-Speech service.
