[Freeswitch-users] bad audio quality

[Michael Collins]

I would start by recording the raw audio on the b-channels and listening to
those. This API command is useful:

ftdm trace <path where to save files per channel> <span_id> [<chan_id>]

You can launch that at the beginning of each call and then call ftdm
no trace as the api_hangup_hook and then you'll have a separate file
for each phone call. Note: this api will create separate files for
inbound and outbound calls.
