Jim Dixon of Alhambra, CA was one of the developers who worked on hardware drivers for the Asterisk Voice over IP software. He took his knowledge and created app_rpt which then allowed Asterisk to function as a radio repeater controller usable by radio amateurs and commercial users. On the amateur radio side, this grew into a VOIP linking system for repeaters that is known as Allstar.
Steve Rodgers announced on the app-rpt-users mailing list that Jim passed away on December 16, 2016.
Jim’s contributions to IP telephony and to the amateur radio hobby were significant and he shall be well remembered.
