The rtpdir bridge - to bridge EchoLink, IRLP, D-Star and Asterisk by Scott, KI4LKF (2007)
This was one of Scott Lawson's first projects. From this project he went on to develop some of the first open source programs for D-Star. At some point in 2013 he discontinued his work and was no longer answering emails.
While Scott may be gone from development, fortunately a lot of his software has been archived and mirrored. His code has also been the base for several forked projects, that are derived from initial work.
Ver 1.60 local mirror: rtpDir bridge irlp_echolink_asterisk_160.zip
Unfortunately Scott destroyed the source code for rtp_Dir. This is a copy of the very last release he made of it for Linux and Windows. But it will only run on an x86 system's not on any arm based systems.
