[Freeswitch-users] Can FS PBX send DTMF(INFO and RFC.2833) on receiving DTMF(INFO or RFC.2833)?

Btw, Brian, I am fully aware that this is not a desired behavior, but I would have to overhaul a bigger system (including lots of Q.E testing) to fix it on our side.
Big impact, otherwise I would do it, not look outside of the system for a hack.
Thanks for your help.

I know it usually is one or the other but that's how one of our legacy server pair works. I wouldn't ask for it if I wouldn't need it.
Is there a way I can get this working from the FS PBX side? 
Thank you.

Thats only for reception.   Notice 'My SIP trunk needs DTMF as SIP INFO **AND** RFC.2833.’, Why do you need to send both?
