Dial pad doesn't work during phone calls

Hello chandanbv0,

We understand that the keypad isn't working on calls, and we'd like to look into this with you.

We’d like to ask a few questions to help us get a better understanding of the issue.

1. Does the keypad respond as expected when you're not on a call?
2. When you attempt to use the keypad while on a call, do you receive any error messages? If so, what does the error say?
3. You mentioned updating your device; just to confirm is your iPhone running iOS 14.4.2 at this time? Find the software version on your iPhone, iPad, or iPod
4. Does restarting your device correct the issue temporarily, or is there no change? Restart your iPhone
5. When this issue happens, does it appear that the screen isn't responding to touch? If so, this page may help: If the screen isn’t working on your iPhone or iPad

Thanks!

I am having this exact problem. It only happens with certain systems, but until today I could call those systems with no problem (my office voicemail). I reset network settings, I restarted, I force restarted, I tried the mute trick, I tried turning off call waiting. Nothing.

chandanbv0,

Thanks so much for taking the time to answer those questions for us.

Does this happen with every call, or is the issue intermittent? If the issue happens intermittently, does it seem to happen only on calls to certain numbers/contacts?

When did this issue initially begin? Were any changes made to your device before this occurred? If so, what changes were made?

Also, let's make sure the carrier settings are updated. This page explains how to check for a carrier settings update: Update your carrier settings on your iPhone or iPad

Take care!
