API with the aim to support all administration
features available in the Asterisk VoIP server.
Its primary goal is to provide a framework between
Asterisk and multi-platform frontends.

Star Asterisk API is a high performance API that
connects to the manager interface of Asterisk or
to AstManProxy. It is easy to use,
object-oriented, and easy to extend to suit your
particular requirements.

QuteCom (formerly WengoPhone) is a multi-platform
VoIP client. The GUI is Qt-based, and the
Video-over-IP engine is based on the eXosip, oSIP,
oRTP, ffmpeg, and libgaim projects. The eXosip
module is extended by a phApi module, which
implements a high-level, easy-to-use call control
API. It supports PC-to-PC voice, video, and chat.
One can use a standard SIP service provider such
as Wengo to be assigned an incoming number, make
calls to PSTN/cell phones, get voice mail, and
more. In addition to SIP/SIMPLE QuteCom provides
IM functionality using libgaim, so it is
compatible with all protocols supported by libgaim.

to produce a standardized implementation of
Asterisk, complete with Web-based administrative
interface.
