I'm a pure newbi to Asterisk/app_rpt and am trying to learn enough to see if it will work for an RLC-3 replacement for my club. I have four nodes in test mode running on one server using USB FOBs and every time Asterisk starts the four USB FOBs get assigned to different nodes than they were on when Asterisk was shut down. Lsusb shows the FOBs are split with two on each internal USB bus, corresponding to the hardware USB controllers. I get good audio out of all four FOBs every time, just from different nodes than last time. The PC is a home built Intel G2130 of fairly recent vintage. Is there a way to tie a USB hardware port to a particular node so I get the same node on the same hardware every time? This is particularly critical in case of power failure so the site can come back up without operator intervention. Thanks, Cole, AA7RD
