Hangs up while dialing

Hi,

Since purchasing my galaxy s6, the device has been hanging up the call about three seconds after dialing - just saying "call ended".
After dialing a few times the call goes through.
The problem persists with different service providers.
It seems to be a software issue as it resolved one day suddenly after returning from a trip abroad with the device, but has now returned after upgrading to android 5.1... :(
Any ideas?
Thanks!

NOTE 5 Dialing International using AT&T service

I bought the note 5 verizon because they come factory unlocked , once i bought it i put my sim card in it and every single time someone calls me it shows a (+) and their number .. and everytime i try calling back it shows a (011) and then their following number . I replaced my sim card , i called verizon , samsung & at&t and still nothing ... i tried resetting the whole phone and nothing still .. any body has any suggestions before i sell this phone ?

Dialer crashes when dialing.

I cannot make phone calls. The instant I click on the green dial button the stock dialer app closes. I can receive phone calls sometimes. I can send and receive SMS no problem, every time. Data/Internet is not a problem.

• I have trouble shooted at length with my carrier Telus but the problem seems to be with the phone. I have changed my SIM card with a friends. I have factory reset. I have installed the updates to B015.

Nobody in this forum seems to have this problem. I'm not looking forward to speaking English with Huawei customer support...

Problems with dialing a number

Every time I want to dial a phone number I receive an error message that says call not sent. I can dial the second time and call goes through. My wife's 6 edge does the exact same thing. This is very annoying when looking up a number and trying get to connect a call only to have to do it all over again. After the error message the dialer just goes blank and you have to enter the number again.
