[Freeswitch-users] is loopback really 'evil'?

[Adam Kelloway]

Understood, thanks.

I have two esl applications I connect calls between. In my testing with 
loopback, it gave me much better audio quality then if I bridged the 
call to another instance of freeswitch, as my freeswitch instances run 
on virtual machines (see my previous thread "Dialplan bridge results in 
choppy audio"). Of course, the difference is that I ran my two esl 
applications on the same freeswitch instance instead of different ones. 
It would not mind running them on the same one if I needed to, but I 
wanted to make sure that loopback was ok to use.
