[Freeswitch-users] Loop audio file with uuid_displace

[David Villasmil]

Hey Cip,
Haven't tested this yet, but:

uuid_displace uuid start <file> 0 mux

Looks like it would playback the file indefinitely. The downsize being a
and b would hear themselves, but if there's only one leg, that might work.

See you next week!
