Solved SIP Info DTMF not working on Android v16 App

[Roberto Neves]

Hi everyone,
After upgrading to v16, i found that the new Android App does not send DTMFs using the SIP Info method when configured to do so.
To ilustrate that, I present you two call flows from calls that I made almost at the same instant, using the same extension (so, same 3CX Client provisioning configuration) and doing the same things during the call (sending the same DTMF digits at almost the same time), one using the IOS app and the other using the Android app.
Looking to the IOS call flow, we can see the SIP Info messages clearly:

But, when looking to the Android call flow (in wich, I repeat, we sent the same DTMF digits) we can't see any:


Both apps were configured to use DTMF method SIP Info.

I hope you guys give some atention to that, once this is a core functionality of PBXs that is malfunctioning.
I'm available to provide anything needed to help solving this.
Thanks for your time.
Regards.

Make corrections at least in beta. Very necessary for work.
