[Freeswitch-users] How to implement TTS barge-in using FS ESL

[xl127]

Hi Christopher,

That will be great! Thanks and looking forward to your app!

By the way, do you have a quick thoughts about the reasons the FS stucks 
when garge-in occurs?
Otherwise if it is not straightforward to explain it,  just leave it 
alone until your new app comes out.

Cheers,
Xing
