Sunrise Telephone Systems KK has announced the 2010 edition of its A4M Macintosh Telephone System ( based on a Mac OS X port of the Asterisk Linux PBX software.

The A4M software suite turns a Mac running Mac OS X (10.5 and 10.6) into a private branch exchange (PBX) telephone system and Voice over IP (VoIP) server. An optional ISDN adapter provides connectivity to ISDN telephone lines.

The 2010 edition consists of a telephony server, an auto-starter, a configuration engine, several system preference panes and a switchboard application. The Cocoa graphical user interface (GUI) based preference panes are designed to make the task of configuring the telephony server easy and intuitive, following the philosophy of ease of use of the Mac platform.

The software will be supported on all Macs running Mac OS X 10.5 or higher (Intel only). It will become available first for the Japanese market in late November or early December 0 for a retail price of 49,800 JPY (approximately US$579) without ISDN adapter and 78,600 JPY ($914) with ISDN adapter. The user interface is localized in both English and Japanese. International versions will become available in early 2011.

The company also announced that it has ceased all development of free GUI tools for the Macintosh PBX software due to lack of sponsorships and donations. All previously available free GUI tools for Asterisk on Mac OS X will no longer be available for download.
