[Freeswitch-users] mod_fsk not detecting call waiting caller id

[Anthony Minessale]

I already explained that this is not what this module is intended for.
It's intended for 1 FS to send another FS a series of FSK data.

If you are trying to get the original CID tone on a new call the ata
is probably already eating it up?
