DTMF tones not responding. I hear the tones but during automated in-call menus, the tones have no effect. Vodafone say to return the phone for servicing but the problem existed when the phone was new - how is servicing gonna help. Any solutions?</P> Mon, 18 Jan 2021 15:50:09 GMT https://community.sony.hr/t5/l-series/dtmf-failure/m-p/3758827#M7835 rcdurling 2021-01-18T15:50:09Z https://community.sony.hr/t5/l-series/dtmf-failure/m-p/3759201#M7836 <P>Do you mean that you can't hear the numbers tone when you press on them during any call ?</P> Tue, 19 Jan 2021 14:32:06 GMT https://community.sony.hr/t5/l-series/dtmf-failure/m-p/3759201#M7836 Anonymous 2021-01-19T14:32:06Z
