[App_rpt-users] Alternative to WebTransceiver java applet

Hi Everyone,

I agree that the WebTransceiver is a powerful addition to the AllStar
project. I've got several hams who use it on a regular basis for repeater
access, so, I hate to see it go as well.

As we all know, web browser developers are rapidly phasing out all support
for java applets. And, along with this phasing out process, continuing to
make java work is a constantly moving target---every time a browser update
comes down the pipe, you have to go and tweak settings AGAIN make java
work.

The biggest problem I see with "upgrading" the WebTransceiver is replacing
the IAX2 protocol stack with updated version which is modern-browser
friendly. We need to remember that all the hoopla about HTML5 is fine,
but, HTML5 is NOT a programming language--javascript is the programming
language used. Another large component required is the actual audio 
interface to the PC and some supported CODEC for communication across 
IAX2...For this requirement, I believe the WebRTC toolkit, which is 
included in modern browsers, could be leveraged.

So, where can we find a javascript-based IAX2 stack?  ...I know there are
already javascript SIP stacks out there (see: http://www.jssip.net/ ).

Thoughts?
