DTMF tone length

I apologize if this has been addressed. I searched and came up empty.

Is there a way on CM (and ROMs built on CM) to access the option to change DTMF tone length? My voicemail won't recognize short tones for my password.

After a bit of research it looks like a little over a month ago, in CM nightly 15, an edit was made to android_frameworks_base to force phones to always use short DTMF tones. My question is, is there a way I can edit android_frameworks_base (if that's even a file somewhere or section in a file) to undo this and use long tones? Or, can I install a different version of android_frameworks_base and keep the rest of the ROM? That seems like a big ol' conflict that wouldn't work, but what do I know?
The workaround I'm using now is nandroid backup, load a stock FRG83G ROM, change the tones to long, check my messages, reboot into recovery, restore the nandroid backup. What a hassle to do this every day though! There HAS to be an easier way, aside from the obvious "Find a ROM that's not built on CM." I'm definitely getting closer to doing that, but it's also fun to solve things like this. Anyone?

Did you manage to solve your problem? I have the same here...

Although this may not be exactly what you would like to do. if the desire is to enter a string of digits to access a system after the number is called, I found a back door semi fix. Putting a pause between each digit may work but some systems will timeout. I found one can put in a pause after every 3 or 4 digits and systems still seem to be able to decode it yet the total pause length is not too bad.
