Why can I not place calls?

Why can I not place calls? My Samsung Galaxy S7 recently stopped being able to place calls. I can still recieve calls, send and recieve messages and use data. The only this that is not working is outgoing calls. When I attempt to make a call the phone says "dialing" and the after a few seconds, it says call ended and hangs up without ever connecting the call.

"Hi,

Check in the Phone app settings that outgoing calls have not been barred.

Not sure if it is applicable to Samsung, it is on my ZTE android phone, but try the following:

Go to Phone app > more > Settings > call blocking and see if there is an option to block outgoing calls.

(on my phone it is Phone app > Settings > Voice call > call barring > All outgoing calls > enabled/disabled.)

Hopefully this is of some help."

"I know it's a few months ago since this post, however I fixed mine pretty easy. I have a Verizon phone on a T-Mobile network. I set up the VPN how it should be etc etc.

Outgoing calls: Seldomly worked but 90% of the time it would dial out then a few seconds later hang up without ringing.

Incoming Calls: perfectly fine!

Fix: swipe down from the very top of your screen. Click on settings icon > advanced calling > advanced calling turn on/off HD voice and video call.> Turn off this setting. And Voila! Back in business."

So i was trying to figure this out for about 2 days and i think i found it basically it went like this (Home screen ->>> my dialer/contacts app ->>> three dots in the up right corner ->>> settings ->>> More settings ->>> Show my caller ID. Now the important thing about that is when you operator doesnt let you hide your number you cant use the option and it just automatically cancells your call request. Found that working for me :D

I put a new simm in my Galaxy J7 from AirvoiceWireless. I could call it, and send and receive texts. But I couldn't make outbound calls. Every once in a while, in the split second before it dialed, I saw a different number flash across the screen ( not long enough for me to write it down) and then the number I had dialed appeared. But a recorded voice always would say "call cannot be completed - please try again." I put the new AirvoiceWireless simm in my Moto G and it worked fine. I put the Moto's simm in the Samsung and I couldn't call out. So since I could see the problem stayed with the hardware, I called Samsung tech support. She was great. She walked me through clearing the system cache, then had me unhide system apps and clear the cache of 3 phone apps that appeared. No luck. Then she had me bring it up in safe mode.... voila, it worked. So she had me bring it back up in regular mode and it didn't work. She told me to uninstall whatever new third party apps had been installed but the only things installed in the last 4 months were system updates and a few little supporting things for the AirVoiceWireless simms and I didn't know how to uninstall any of those. So next she had me reset preferences on all apps. (settings -> apps -> 3 upper right dots -> Reset App Preferences) That did the trick. Whew! Now I can call out.

"I was also facing the same issue in Samsung S7.

Then i changed the setting in the phone menu

phone menu -> setting -> more settings -> show my call id - > show my number in outgoing calls according to the default operator settings

Hope this helps"
