DTMF Tone on IOS 13 issue

Having tried nearly 20 times to enter DTMF correctly for an 18 digit number and then had to wait two hours on hold to provide the same information to a human operator I can confirm that there is no way you can touch the button for a short enough period to make it work on a bad connection.

I was getting multiple repeats each time I entered the digits, sixes and twos were the most common.

It’s actually not helpful because not everyone uses said “properly” designed systems. I can no longer open my gate or dial into my bank. It’s ridiculous. Just change it back to the old way geez. It’s not something ANYONE cared about being changed. Just set it back to normal and leave it alone or make it an option that I can choose between Apple. It’s infuriating to not be able to open my apartment gate.

What Mr. Finch doesn't understand is that some IVR systems work just fine and are properly designed for their day. I can no longer open the gate to my complex nor the front door to the building with my iPhone. Being in the airline business, I travel a lot. The ability for delivery to my condo depends on opening the gate and the front door. The fact that "short tones are better" doesn't solve the problem and our HOA spent a lot of money upgrading the system only 3 years ago. Android users have no issues!

I was pretty sure this would be the answer provided by T3... It seems there's wrong on both sides. But the carrier isn't to blame.

As far as I know when you experience this issue it often occurs for a particular IVR (not all). But that said , where it involves iPhones, an Android device DTMF will work regardless of the carrier plan.

I’ve mentioned before that when you send touch tones, you are not actually sending them to the other side of the call, but rather your phone tells your cellular provider to generate a touch tone on their end of the connection.

If their equipment isn’t properly doing this, the sent tones can fail.

This not true as the short code has all the same pitch long tones have various notes

come in Apple sort it out

Also there seemed to be a difference if the number was manually dialed vs. entered as a contact (with pauses and what not, to get through ivr prompts)

Same here. I need to press and hold 9 to open my security gate. Now you can’t hold the number down. The tone is too short. :(

That's fine, but if your carrier does DTMF regeneration any phone used on their network will act the same way.

Are you on the Verizon Network?

Yes mine works “sometimes” it is random. The only common thing I have found is apple phone on T-Mobile/sprint other combinations don’t seem to have the problem.

Sprint fixed the DTMF problem on their end. No idea how they fixed it but it works now.

That's not the case. Voice over LTE (VoLTE) is a feature that allows voice calling over our 4G network using compatible devices. It allows you to remain connected to the 4G network during calls, which means you can continue using 4G mobile data while making and receiving calls.

Here is a detailed explanation of what VoLTE is: https://www.cio.com/article/2393973/voice-over-lte-explained-better-voice-quality-coming-soon-to-your-4g-phone.html

This trick worked on my iPhone11 (iOS13.3) to solve the issue.

Previously i was able to navigate through IVRs in this same phone. But since last 1 month i was not able to do so. Must be a problem cropped up in the recent updates of iOS.

Has anyone figured out a real fix to this issue? I don’t have those setting to do the work around in my iPhone 11. It’s crazy this is still an issue and very frustrating that someone is blaming the IVR systems.
