Issue with Barge-In

[kenn10]

@pbxgeek I am experimenting with barge-in to an existing call (*33+extension). The lua script requires a password, which I have commented out for testing.

The problem I have is that every time I try to barge into a conversation on the line in question, the connection is robotic, has loud background digital noise, low volume voice playing at octaves higher than the real voice on the line. I suspect this may be related to FreeSwitch issues but I'm not sure.

This is on FS PBX version 1.8.5 on Debian-13.

In my experience, this typically occurs when two legs are on different codecs. Freeswitch attempts to transcribe a conversation while passing it to the barging phone, which results in the sound you described.

Before the answer command in the dialplan try to set or export (i forgot which one does the trick) absolute_codec_string=PCMU assuming the SIP call to the outside is using G711U
