It’s been my experience that the most reliable setting is “InBand+INFO” because it sends a simultaneous inband and out-of-band DTMF, although you can try the other out-of-band DTMF settings if you prefer.

See page 153 in the admin manual for this phone:

Voipo use to have 10 digit number to access voicemail, but I believe it’s not supported anymore.
Their only supported methods can be found here:

Thank you so much for your help! Changing the "DTMF Tx" setting to "InBand+INFO" worked! I figured it had something to do with the DTMF tones, but I had no idea what settings to change. Everything seems to be working perfectly now.

I can live without a 10 digit number to call for retrieving messages.

Thanks again for all your help! This forum is awesome!
