DTMF Problem (Digits not recognized)

[Fede]

Hi,
we have a problem with DTMF digits.

If I configure a Cisco with a FusionPBX extension I can't access the voicemail cause it doesn't recognize the typed numbers.

The only way to make it works is enable SIP Info, but the problem is that not all phones have it.

Any suggestion on how solve it?

Thanks a lot

Does this only happen on speakerphone? We had issues on Freepbx where the digits would not be recognized sometimes when the SPA phones were using speakerphone.

No, it never recognize the digits. Maybe is because is using not RFC2882 but a more evoluted one?

We tryed also with snom and same result...also tryed different installations

Thanks,

@Oswaldo Jr. Do you/or somebody know any solution without touching the endpoint? Like Freepbx do

Thanks

In Advanced -> Sip Profile:

Internal and External

Change or insert dtmf-type like this image:
