I've found (I'm a SPA-2100 user), that to do what you're trying, and adjusting the "DTMF Process AVT" and "DTMF Process INFO" settings from Yes to No (one or the other, none, or both) to be by far the most reliable way of getting touch-tones to work in hard cases, but with this restriction: you have to be set to "Auto" when you do that. The fact that you're set to "Inband" while doing these adjustments leads me to suspect you're creating the problem for yourself.

Voxalot VM works fine with the SPA set to "Auto" and the two process categories above it set to "Yes", but that isn't always the case for all providers calling out to the PSTN. However I'd suggest that toggling away from Auto on the one hand, and toggling between yes/no for the two process categories on the other, are two mutually exclusive ways of adjusting DTMF reliably in a Sipura.
