Hello Everybody,

How can I send DTMF tone string from my Nokia 7610 running Symbian OS 7.0s i.e. 2nd Edition FP1 ?

I know it is possible in Symbian 9.1 as there is a method SendDTMFTones in CTelephony. But I have found no such functions in 7.0s SDK or 8.0a SDK.

Is it possible actually in 2nd Edition FP1(7.0s) or FP2 (8.0a) ?

Please let me know, if you know anything in this regards, it will b very helpfull to me.

Thanks in advance,
Tushar

There's always the dirty fallback solution to use sound clips for the individual DTMF tones.

Hello Puterman,

Thanks for your reply.

Let me tell you the problem in more details.
I have tried using CMdaAudioToneUtility to play DTMF string during call connected state, But no sound in either side. But it plays the sound as a alone application.

May be the cause is the channel is already taken by the telephony.

What do u suggesting ?... using CMdaAudioClipUtility ? plz help.

Thank you for your time,
Tushar

Yes, that's what I was suggesting.  I've only used it with S60 1.0 phones, but it should work fine with 2nd edition as well.  IIRC you have to set a specific magic priority value to play audio to the uplink on S60 2 devices.

Re: How to send DTMF from Symbian 7.0s phones
Hi Tushar,

I have same problem.  Right now i am working  with series 60 FP2 Sdk. I tried to use CMdaAudioToneUtility :: PrepareToPlayDTMFString().

I got the sound on emulator, but when i am testing on nokia 6680 , i didnt get any sound as well as MatoPlayComplete Callback never gets called not matter wheather call is active or not.

Can you please suggest me what is the right way to generate the DTMF tone on device and send it to another device during call is active ?


Thanks and Regards,
Dip

Hi Dip,

Did you do that? If not, try using SimulateKeyEvent and other related Simulation functions. Some one said it has worked, I am also trying.

Hi tusharbhatta,

I used key simulation process. But the problem is phone application supposed to be in foreground then and then DTMF tones get generated and i want that my application supposed to be in foreground rather than phone application.

If i send key event to phone application when it is in background, DTMF tones not get generated.

Regards,
Dip

Hi Dip,

There should not be any problem to generate tone whether your app is on foreground or not. Probably the tone generation code have some problem. Did u Check that tone is generated without call setup processes?

Try with different SimulateKey functions available in the SDK.

Best of luck,
