TC software support for DTMF letter values

Hi!

Got a question that I can't find a documented answer for.  On endpoints running any version of TC software, is there any way to get the endpoint to generate the DTMF tones for A, B, C, or D? 

My gut feeling is no, if only because the graphical DTMF pad does not have those buttons (only 0-9, *, #).  The reason for asking is a customer is trying to call into an AT&T bridge which has one of those letters in the PIN.

Thanks!

You can do it via the command line:

xcommand DTMFSend DTMFString: A

or, you can send the whole PIN at once, ie if the PIN is 1A2B3C4D5 you can:

xcommand DTMFSend DMTFString: 1A2B3C4D5

Hi Wayne,

Thanks for the answer.  After reading it I realized I hadn't actually tried sending a letter DTMF.  The perils of internet research I suppose.  ;-)  Looking in the logs of my endpoint I saw that I was receiving the letter DTMF from the endpoint I was connected to.

Thanks again!

As a follow up, here are some other hopefully helpful tidbits;

- The letter (A, B, C or D) must be capitalized in the command string

- The codec will not send anything outside of the scope of DTMF (i.e. E-Z)

 

Thanks!
