[Freeswitch-users] Deliberately adding delay to all calls

Mon Jan 29 19:30:49 UTC 2018

OK, doing

<action application="export"
data="nolocal:absolute_codec_string=PCMA,PCMU"/>
<action application="bridge" data="sofia/gateway/FreeSWITCH/201"/>

Seems to take care of the transcoding.

I'm going to try and move this back to one server.
