Dialogic D4pciu Stops Playing Dtmf

[mrcharles]

When I play back DTMF digits using the Dialogic D4PCIU card, it cuts of the playing around the 30th digit. It did not do this when I originally had a voice modem. A portion of the log where this occurs is below:

This would be Dialogic's own internal limit on how many DTMFs it can generate per "play DTMF" call.

 

Solution is fairly straightforward:

 

You will need to split the sending of DTMF tones across two or more Play modules.

 

You can use Evaluate Expression module and its string manipulation functions:

left(), right() and mid(), to split up a long DTMF string into manageable lengths, see: http://www.voiceguide.com/vghelp/html/modEvalExpr.htm

 

Then save individual DTMF strings into separate RVs and then use those RVs in the Play modules...

I just used the shntool and made a .wav file of the tones with pauses. That seems to work fine. Is there anything I need to keep in mind when doing this?

[SupportTeam]

That solution will work fine as well.

There are no limits on the length of .wav files which you can play with Dialogic cards.
