Several users have reported problems when trying to make a call. The reported problems include, but are not limited to, call failing and no sound.
Fix
There has been similar Siri related problems with outgoing calls where there is no sound while a connection is established. It has been reported that updating to the latest iOS fixes this problem.
If you have a call failing issue and updating your iOS does not fix your problem, try each of these steps until you resolve your issue:
- Make sure that you are in range of the cell network by checking cell signal indicator bars.
- Reset your network by tapping Settings > General > Network
- Reset your iPhone by holding down the sleep and home buttons until the Apple logo appears
- Try Settings > phone > show my caller ID. Just visit and let the device load your settings.
- Try disabling airline mode.

Try this
General- Date&Time- Set Automatically Turn it OFF
the set the Time Zone to THE PALCE WHERE YOU BOUGHT THE IPHONE After that just change the time to your current time !!
For an example i live in sri lanka but i bought the iphone from singapore so i changed the time zone to singapore and adjusted the time to my local time and IT WORKED

Same here.
The phone was working fine until yesterday. Outgoing calls Failing with error “Call Failed”.
Earlier the phone was not working at all. No Outgoing. People calling me could hear the ring, but the phone at my end was not ringing. I updated the Firmware to 5.1 and I started getting incoming calls and SMS started to work.
I finally restored the phone, yet no luck.
The only thing what I did yesterday was I checked a friend’s New Micro SIM in my phone.
Any suggestions
???
Thanks

If the Show My Caller ID option inactive, you cannot change this option for some reasons. You can use cydia tweak called Caller ID SBSettings Toggle to change caller ID option on iPhone.
This works for Me

Try turning on/of one of the others in Settings>Phone> Call Fowarding/Call Waiting…Works for me…

this works, but this is not a permanent solution. Every time when you turn off mobile power and turn on the problem continues. and you need to do all above things
Will apple find a permanen solution???

I am with tmobile and have the 4s, phone displays full signal and has the operator name on screen. Calls fail and no incoming calls can get through. The only way I can fix this is by turning phone off and on. As the phone displays signal as full when it actually is not connected to the network, I can not tell there is a problem until someone tells me my phone is off or I try to make a call and get the call failed message. Complained to tmobile tested new sim still problem. Tested sim in other phone not apple, no problems. Advised to contact apple done so explained problem and what I have done to try and rectify problem. Told it is a fault with the phone, they booked me in to exchange for a new one. Less than 1 months warranty left. That’s good service.

i was able to call until morning when suddenly my iphone showed error CALL FAILED.
I inserted my sim into my colleagues phone in order to verify whether it was a sim problem or iphone issue.
and guess what i was able to call without any problem as a result no problem in the sim.
then i re-inserted the sim in my iphone in haste and checked the settings: settings>phone>show my caller id. let your iphone load its settings.
tried calling and it worked (y)!
