Marco, There are currently a number of reasons we are still using Asterisk 1.4.x The Asterisk module that makes ASL possible is app_rpt. Dixion and his contemporaries made chan_usbradio and chan_simpleusb which were written for Asterisk 1.4 and 1.44. (maybe others??) These chan 'drivers' are the HMI (human-machine-interface) to connect software to hardware for analog signal handling/processing. When all was working to the way Dixon wanted, he had absolutely no reason to change this as he thought it was perfect. Him and I got into many discussions about this, and we see now how it went.. The module app_rpt was discontinued in distribution by Digium, owner of Asterisk, release is version 11... I think, maybe it was 1.8. I need to find the source to verify that. Either way, Digium quit supporting and shipping app_rpt with their asterisk source code some years ago. Jim Dixion and the creator of Asterisk and Mark Spencer, created app_rpt for connecting radios to Mark's adolescent-stage creation, for use of radios with a VoIP exchange system - making it RoIP. No one has stepped up to the plate to "patch/fork/whatever" app_rpt to the later versions of Asterisk. This kinda needs to happen as the world makes a very slow, but inevitable transition to IPv6. Which the current version of Asterisk we are using does not support. (Sure there are work-arounds, but those are getting complicated to make work *reliably*). In the mean time, bleeding edge technology and software are filled with new engineering problems - not stable. The version we are using is stable, and secure - the weak link is the un-educated user. (think: new and/or bad car driver) Also consider this- most of us who have cars,trucks, boats are using a technology well over 100 years old. The outside of the magical machine has changed some, but in the end the fundamental operation of controlled explosions turned into mechanical energy i.g, shaft power, is the same. If you have an electric car, the induction motor is the same principal design that Tesla made. So, here we stand. Who gonna do it? If someone is complaining about it, but not willing to actually do something about it, that someone should be quiet. Take it as you see it. Everyone is responsible for how they tune their own receiver.

Thanks in advance, 73 Marco IW0RED.
