About

FreeSTAR SIP-DMR Portal

This wiki documents the sip-dmr-exchange stack: a SIP-to-DMR portal that lets VoIP users join DMR talkgroups through a per-call bridge container.

It is maintained by the FreeSTAR Network for use with FreeSTAR Everywhere and is intended to be reusable by other amateur radio groups running their own instances.
