AsteriskJS is a package, written in Typescript, that helps you to connect your code to a Asterisk IP-PBX Phone system. Besides that this packages helps you with developing advanced dial plans (using AGI), this package makes even possible to use the Asterisk Management Interface (AMI).
However we're using this package already internally. This package isn't ready for production yet. We're currently in the development stage. So please don't use this package in production environments. We're trying to bring this package as soon as possible to a stable version. Please stay tuned until then.
