SvxLink

The biggest change in this release is that a
third-party DTMF decoder is now used in the
SvxLink server software. This is a much better
implementation than the one used previsously.
Other than that, it's mostly bugfixes and
compatibility changes.

Support for remote receivers linked over the Internet has been added. To be able to use multiple receivers, a simple signal strength detector was implemented. CTCSS tone transmit has been implemented and the CTCSS squelch detector has been improved, which makes it possible to run SvxLink with the squelch open. DTMF muting and squelch tail elimination has been added, and there are a couple of other changes and bugfixes.

The bug that made the SvxLink server crash when recording voice mails on distributions other than Fedora has been fixed. A couple of other bugs have been fixed. A new "connect by call" feature in the EchoLink module has been added. The voicemail module can now send a notification email when a new voicemail arrives for a user. Log entries in the log file are now timestamped. It is now possible to use both DTR and RTS together for PTT, which is required by some interface boards.

A serious bug in the networking code that caused the SvxLink Server to crash or hang was fixed. A new module for handling voice mail was added.

The repeater controller logic has now been thoroughly tested and is considered stable. A new event handling subsystem written in TCL makes it easy to customize the behaviour of the software at different events. Also, it is now possible to connect two logic cores together to form a link between, for example, two repeaters.
