The Kotlin SDK for Vonage provides a rich set of features and a dedicated annual conference, surpassing other established JVM languages like Groovy and Scala. It offers a resource-based approach to making API calls, which simplifies the task of providing an ID for nested resources, reducing boilerplate code and improving developer experience. The SDK also leverages Kotlin's neat features, such as nullability, named, default, and optional parameters, lambdas for builders, and extension functions, to provide a more idiomatic and elegant way of working with the API. Additionally, the SDK is well-documented using KDocs and has 99% code coverage through end-to-end integration testing. The development team welcomes community input and suggestions, and there are plans to keep up with new features and APIs in tandem with the Java SDK, build tutorials, integrations, and miscellaneous improvements based on user feedback.

This article discusses integrating an external Automatic Speech Recognition (ASR) engine with Vonage AI Studio to enhance the functionality of voice-driven applications. The integration uses the Deepgram ASR Engine service provider, which offers more control over accuracy, transcription speed, and custom vocabulary compared to the built-in ASR solution in Vonage AI Studio. The article guides readers through setting up the integration by creating a Deepgram project, retrieving an API key, and linking a phone number to the application. It also provides instructions on how to set up the HTTP Agent, run the ASR application locally, test the sample AI Agent and ASR Connector, and troubleshoot potential issues. The integration enables efficient handling of PSTN-type calls and can be extended to support additional communication channels, such as SIP calls or WebRTC clients.

The E.164 international standard defines a phone number scheme that ensures each user worldwide has a unique phone number, simplifying international calls and reducing the risk of dialing the wrong number. The standard format is [country code] [national destination code] [subscriber number], with a maximum of 15 digits, where country codes are represented by prefixing them with a plus sign (+), national destination codes identify specific areas or networks within countries, and subscriber numbers are individual phone numbers assigned to users. Various examples illustrate how different countries' phone numbers can be represented in the E.164 format, including those for the US, UK, Spain, and Germany. The standard is used by many APIs, such as Vonage Network APIs, which require API consumers to follow this format when calling certain endpoints. To validate an E.164 phone number, developers can use existing libraries like phone or phonenumbers, or build their own validator using regular expressions.
