Hello Teams Community,
i have a colleague who is having this problem.
They can call out to PSTN when in conference. After the call is completed sometimes we are required to dial digits for Auto Attendants (dial remote extensions or menu options).
If someone picks up on the other end instead of automated systems it works ok.
We use the dial pad to select the Auto Attendant option/extension we hear the dial tone but it is not sent to the other end,
It only happens when we are in a conference. If we call an external number directly we are able to use DTMF and AA options/extensions.
