Calls dropping on iPhone

If you are experiencing intermittent silence or drop or the call itself is disconnected during voice calls on your iPhone, there are a few things you can try to fix the issue:

1. Poor signal strength can cause dropouts or silence during a call. Try moving to an area with better reception or switching to a different network if possible.
2. Restart your iPhone --> Restart your iPhone, iPad, or iPod touch - Apple Support
3. Force Restart your iPhone --> Force restart iPhone - Apple Support)
4. This may help too. Go to Settings > General > Transfer & Reset > Reset > Reset Network Settings.
   1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
   2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or Remove configuration profiles on iPhone in this guide.
   3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
   4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
5. Check if there is a software update available for your iPhone. Go to Settings > General > Software Update.
6. Check if your audio is not connected to external Bluetooth speakers.
7. Few other reasons why your device keeps Muting / Dropping / Disconnecting Calls or encountering Call Failed.
   1. Your device's cellular signal Is weak.
   2. It's Raining (Cats & Dogs) in your area or in the area where your device is hooked.
   3. The Cell Tower is Overloaded / Heavy Traffic (Telecommunication)
   4. You've misunderstood your signal strength
   5. You are moving and the signal weakens while changing from one tower to another
8. Other culprits may include the following:
   1. Bad Weather: Precipitation can leak into phone cable lines and cause disruptions. Lightening, even at a distance, can disrupt the connection.
   2. Wireless interference: Power lines, radio, or television. transmitters, transformers, and other electronic devices may cause noise on the phone line. --> Resolve Wi-Fi and Bluetooth issues caused by wireless ...
   3. DSL services: The high-frequency signals coming from DSL (digital subscriber line) devices sharing the phone line can create problems for other technology connected to the line.
9. Try to turn on Airplane mode, wait for 10-15 secs, and turn off airplane mode.
10. Check the health of your device's Battery. Change if below 80%
11. Take the SIM out and Put it back again, Change your SIM, if it is damaged
12. Time to contact your Carrier / Change if required

I have been searching threads for iPhone dropping calls and because of the research I have done and all of the methods listed to different customers that have not worked I have come to the conclusion it is not the network as this problem is happening on multiple networks. I strongly believe it is an Apple issue. Here is my primary reason for determining it is the Apple software: When I make a call with my iPhone 14 pro it drops my calls within 2 minutes every time. It is obviously using the network which in my case is Verizon. However I'll throw another scenario into the mix. I have a bluetooth adapter attached to my cordless phone system so I can link my cell phone to the home phone and enjoy all of the benefits of having multiple phones to take and make phone calls with. The device works flawlessly. Interestingly enough since the cordless phones are using my cellphone signal and the cellphone it is connected to the Verizon network there is not a problem with the network. When I answer a call or call someone on my cordless phones using my cellphone data I have NO dropped calls. I am able to have any length call without dropping the call. If it were a network issue the call would also drop on my cordless phones. In my opinion there is some sort of handshake between the network and iPhone that is not working correctly and thereby dropping the calls. I challenge Apple to find this issue and fix the problem. I really don't want to change my cell phone to different manufacturer as all of my devices are in the Apple family. If Apple can't fix the issue I will have no other choice but to try another cell phone manufacturer.
