[Freeswitch-users] Subject: Re: Tone detection issue

[Alexandru Covalschi]

Thanks for your reply Christopher!

Can you please specify how should I edit spandsp.conf (tones section) to
add my tone? I was trying for hours but didn't get any result, I just can't
get the logic and I'm struggling.

Cheers,
Alex
