I able to dial to PSTN number via MVA feature but not recognizing the DTMF once the call established. for example, dial to credit card number via MVA but not recognize the language selection.

Is this normal behavior not allowing DTMF via MVA or a solution?

Advise please,

Please advise whether DTMF support when make a call via MVA. this is kind of mid-call control and want to know whether it support by default.
