[ingvar_e]

I have seen in postings on this forum both "."  and ","   (period and comma) meaning a pause in sending DTMF-tones.  I have not found the "Official" definition. Is there one?

How i it implemented, Is it the API that just makes a pause?

PhoneCall.sendDTMFTones does not support pauses (commas or periods).  Your application will need to wait/sleep between tones if you want to have a delay between tones.

Thats what I thought. Thanks for confirming it. I have already put my sending in a separate thread and use an initial sleep for the benefit of the PBX. The Nnotion that comma or period works for pause seems to be common

Commas work in the phone application, but not in the sendDTMFTones method.

>Commas work in the phone application,

Hmm,  sort of.  I placed a "comma ( ",") as the first character in the string containing the number I wanted to call. Nothing happened. No call placed, no error message. Nothing, Nada, Zero, Zilch.

like this:

Number = "," + phoneNumber.trim();    //Nothing happens

//  Number = phoneNumber;                //This works, call is placed

PhoneArguments pa = new PhoneArguments(PhoneArguments.ARG_CALL, Number,false);

 Invoke.invokeApplication(Invoke.APP_TYPE_PHONE, pa);

A phone number that starts with a comma instructs the phone app to call a preset number, wait, and then insert the DTMF tones.  This preset number is typically a company/work number that allows a user to just store the extensions of co-workers in their address book. 

If this preset number hasn't been set, you should get prompted to enter it the first time you try to dial a number that starts with a  comma.

So, a comma has two functions  :-)

[MSohm]

Yes, depending on where it is in the numbers being dialed.

I guess its to confuse the enemy
