Open Source Linux Telephony Software

This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the source code distribution. NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c

Chopped LIVR takes YAML input and generates Asterisk dialplans. It is primarily useful for generating IVR (Interactive Voice Response) applications; however, it may be used as a tool to generate any Asterisk dialplan. Chooped LIVR also incorporates control structures and functionality enhancements to the base Asterisk dialplan language.

Cress (Communication Representation Employing Systematic Specification) allows graphical description of a wide variety of services such as in data communications/telecommunications, but Cress is not limited to this. The approach allows services to be described graphically as (work)flows of activities. Cress diagrams are automatically translated into formal languages for rigorous analysis and verification, and are also automatically translated into implementation languages for deployment and validation. Cress aims to make service design as easy as possible without requiring specialist development knowledge. It simplifies service creation to drawing diagrams, clicking buttons and defining a few tool parameters. All key functions of Cress can be controlled from the Chive diagram editor. Cress is written using portable and widely used languages (Perl and Java). It can be extended by a developer for other kinds of services that can be characterised by activity flows.

DialogPalette is a visual, integrated design environment for the creation of telephony applications running on the Asterisk Open Source PBX.

ECharts is a state machine-based programming language for event-driven systems derived from the standardized UML Statecharts language. ECharts has a proven track-record in a large-scale commercial deployment. Take a look at what ECharts has to offer!

Java version of Dialogic's SwitchKit API. This API is actually a more "Java Centric" API, with listeners, filters, and a very extensible and modular framework that finally uses JNI to access the native libraries provided by Dialogic.
