Ring time issue on my iPhone 13 after iOS 18 update

Easy fix--after spending an hour with Apple who couldn't help. I contacted Telstra and they told me to turn off Live voice mail --fixed! Settings/Apps/phone/live voicemail--OFF

It does indeed apear to be an ois update issue. Three hours on the phone testing with Telstra has led to this conclusion.

If Live Voicemail is turned on, then the ringtime before Telstra messagebank is reduced to 15 seconds. I have 30 seconds programed into the Telstra Network but that is overridden with Live Voicemail turned on. This has only happened since the last OIS version update. My wife's phone, also on the latest OIS vesion, has the same issue.

If Live Voicemail is turned off then I do not receive a text message from Telstra advising that I have a Voicemail.

I hope that Apple will fix this in the next update. I am old and slow so 15 seconds does not provide sufficient time to stumble to the phone to answer it :)

When your iPhone sends incoming calls directly to voicemail or is disconnected after a ring, it might be due to various reasons. This can occur if the recipient's phone is powered off, in a low signal area, or if they have enabled the "Do Not Disturb" mode. Additionally, the contact's number may be blocked or marked as spam.

1. Check your DND status - If you're experiencing issues with notifications or incoming calls, it's important to check your Do Not Disturb (DND) status. On most devices, you can access this setting by going to "Settings" and selecting "Do Not Disturb." Make sure DND is turned off or adjust the settings to allow desired notifications and calls to come through.
2. Check BedTime status - If you're using the Bedtime feature on your iPhone, you can track your sleep patterns and set a schedule for waking up and going to bed. To check your Bedtime status, open the "Clock" app and tap on the "Bedtime" tab. Ensure that your sleep schedule is accurately configured, allowing your device to provide sleep analysis and reminders accordingly.
3. Check your Sound Volume - If you're experiencing low or no sound on your iPhone, it's essential to check your sound volume settings. You can adjust the volume by using the physical volume buttons on the side of your device or by going to "Settings" and selecting "Sounds & Haptics." Ensure that the volume is turned up and not muted.
4. Check your Ringer switch - If you're not receiving any sound notifications for calls or messages, it's important to check the position of your device's ringer switch. Depending on the model of your iPhone, the ringer switch is located on the side or top of the device. Make sure the switch is not set to the silent or muted position.
5. Check Call Audio Routing - If you're having issues with audio during calls, such as not hearing the caller or distorted sound, you should check the Call Audio Routing settings. On an iPhone, you can access this by going to "Settings," selecting "Accessibility," and then "Audio/Visual." Ensure that the audio routing is set to the desired option, such as Bluetooth, speaker, or automatic.
6. Check Auto Answer Calls - If your iPhone is automatically answering calls without your input, it's important to disable the Auto Answer Calls feature. Go to "Settings," select "Accessibility," and then "Touch." From there, disable the "Auto Answer Calls" option to regain control over incoming calls.
7. Check Connection with Bluetooth Audio - If you're having trouble streaming audio from your iPhone to Bluetooth devices, it's crucial to check the Bluetooth connection. Make sure Bluetooth is turned on in the device settings, and try reconnecting your iPhone to the Bluetooth audio device. If the problem persists, you may need to unpair and repair the devices or troubleshoot further using Apple Support resources.
8. Check whether in Headset Mode - If your iPhone seems stuck in headphone mode despite no headphones being connected, it could be a software issue. You can try solving this by cleaning the headphone jack with compressed air or gently inserting and removing headphones a few times. If the problem persists, you may need to seek assistance from Apple Support for further troubleshooting steps or possible repairs.

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution!

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

Thank you for that advice Redhills and it did indeed fix the problem of the quick cut off of the ring. But I encountered another snag when I tested the fix. I got one of my contacts to ring my phone, let it continue to ring and to let the call go to voicemail. Unfortunately this did not work and instead of going to voicemail their phone stated that my number was not recognised!

The update DID cause problems to the number of rings If you notice the volume dropping that is usually because you are LOOKING at the phone as it is ringing. iPhones recognise your face and it is assumed that you know that your phone is ringing and won't need full volume to tell you so. Merri

I have this same issue too. The volume of the ring also drops after the first ring. I have checked the suggestions made above and unfortunately it has not addressed the issue.

Glad it helped. I didn't have any issue with my number not being recognised though---my husband and other friends have all called me and been able to leave voice messages as usual.

I have an iPhone 11 and have exactly the same issue since my last update.

Had exactly the same problem…… spent an hour with my service provider. I couldn’t solve the problem. I Followed the above instructions, and my iphone is working brilliantly now. Thanks.

Perfect, thanks heaps Redhills2. Plenty of friends will be thankful too having the same issue

Thank you Redhills2 🙏

My iPhone has also done the same thing after being updated.
