I have noticed a couple of DTMF issues in the forum but mine is different. Since updating from Elastix 1.3 to 1.5, I can not access most of my IVR using my cell phone. I have 4 options. Options 1-3 roll over to my "you pressed the wrong key" option. If I press 4 which sends the call to my cell phone, it works. All options work with a landline. Everything worked with my call phone with 1.3. Any ideas?
