My question is: since my provider is not doing RC2833 dtmf (even though they say they do), is there another way to get dtmf to work?

You can try info and tone detection just in case one of those is being used, but it appears from your message that you have attempted both of these already. I think it's time to find a more reliable provider, or try to persuade your current provider to fix it (the latter is probably a waste of time and effort, however).
