Dialing extension numbers not connecting to IPhone 8

Hi I keep trying to dial a extension number but it rings there side but I get no dialing tone. They cannot hear me there side but it definitely rings. I don’t get anything my side. Have tried adding the extension number to the original number but it doesn’t work at all.

Works fine on family members iPhones just not mine. Any ideas how to solve it. I’m in the UK. Thanks

iPhone 8 Plus

Hi Lila61,


Thanks for using Apple Support Communities. It sounds like you’re having trouble dialing extension numbers. I’m happy to provide some steps that might help. If you haven’t already, I suggest restarting your iPhone to see if the issue persists. 


If it does, I’d check to see if there are any profiles installed on your iPhone that may be affecting this. You can check by tapping Settings > General > Profile.


If nothing is there, I suggest trying the steps in this article:


If you can't make or receive calls on your iPhone - Apple Support


Lastly, you’ll want to reach out to your carrier to make sure everything looks good on their end. If it does, contact Apple Support for further assistance.


Take care.

Thank you for the suggestions but none work. My carrier service is up to date and they suggested i contact you. The extension can ring my phone but my phone will not connect... it will ring the extension but when someone answers my iPhone goes dead... no dial tone.... nothing and they cannot hear anything. However the call does not end until either they hang up or me. It’s very frustrating.
