When making outgoing calls it keeps ringing during the call almost everytime...

Hey there siteshop,

It sounds like you are still hearing the phone line ringing even after the person you call answers the line. I would try the troubleshooting outlined in this article:

iPhone: Troubleshooting issues making or receiving calls

https://support.apple.com/kb/TS3406

1. Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.
2. Ensure that your software is up to date:
   1. Check for a carrier settings update.
   2. Check for an iOS software update.
      Note: Some updates may require a Wi-Fi connection.
3. If the iPhone has a SIM card, reseat the SIM card.
4. If the iPhone 4 or iPhone 4s is on the Verizon network, dial *228 from the iPhone and select option 2 to update the Preferred Roaming List (PRL). The PRL determines the cellular towers the phone uses for cellular service, selecting those with the best signal strength.
5. Reset the network settings: Tap Settings > General > Reset > Reset Network Settings.
6. Try to make or receive calls in another location.
7. Attempt to isolate to one network band:
   • If you're having the issue on LTE, disable LTE, if possible, and try again.
   • If you're having the issue on 3G/4G, disable 3G/4G, if possible, and try again.
8. Contact the carrier to check the following:
   • Your account is properly configured to use the specific iPhone that has the issue.
   • There are no localized service outages.
   • Your account doesn't have a billing-related block.
   • Your calls don't have errors on the carrier system.
9. Restore the phone as new.

If the above steps don't resolve the issue, go to an Apple Retail Store, carrier, Apple Authorized Reseller, or contact AppleCare to send the phone in for service.

Thank you for using Apple Support Communities.

All the very best,

Sterling

I did all of these steps but I still have the issue.

Thanks.
