The SvxLink Server is a general purpose voice services system, which when connected to a transceiver, can act as both an advanced repeater system and can also operate on a simplex channel. One could call it a radio operating system since it sits between the hardware (transceiver) and the applications (modules) and handle basic system services as well as input and output. SvxLink is very extensible and modular. Voice services are implemented as modules which are isolated from each other. Modules can be implemented in either C++ or TCL. The project also includes Qtel, the Qt EchoLink client, is a graphical application used to access the EchoLink network. This release includes a new revision of the SvxReflector application, which is meant to be used as a center point to link SvxLink nodes together. You can build only svxlink server (no Qtel) by passing QTEL=NO to the script: QTEL=NO ./svxlink.SlackBuild Opus is an optional (and, based on the audio quality, suggested!) dependency available from slackbuilds.org You need a "svxlink" user and group: # groupadd -g 286 svxlink # useradd -u 286 -g svxlink -d /var/spool/svxlink -s /bin/false svxlink The recommended uid/gid is 286, you may want to check http://slackbuilds.org/uid_gid.txt for other recommendations. To run svxlink server you will need the svxlink-sounds package. You may want to check the rc.svxlink scripts for startup options.
