The table below outlines all the ports used on your PBX that you need to open on your hardware firewall if you want outside users to have access to things. These are default port assignments for new installs, but most can be changed by the user post install. Legacy versions may have used different default port numbers (notably http provisioning) and the original port numbers remain unaffected when the system is upgraded. Imvu official download.
Yate client(Qt) - launch the Yate client; Yate Cosole - launch the Yate server Yate Web Site Installing Yate from SVN Requirements. TortoiseSVN; at least Visual Studio 2005 Compiling Yate on Windows. To compile please build the 'YATE' project - it will build the library and all modules without external dependencies. Before using the interface, the WebGUI must be given write right to Yate's configuration directory. The command that has to be run as root is: chmod a+rw /etc/yate (If yatebts is installed from package.) or chmod a+rw /usr/local/etc/yate/ (If yatebts is installed from sources.). A gateway for engines with a J1708 serial interface to a NMEA 2000 marine digital network. It supports three protocols that work over J1708: the standard J1587 used by many manufacturers, the proprietary Cummins KCM-II and the proprietary Volvo Penta protocol used in engines with EDC I.
