Call Failed - Only connected to wifi

[Eric-PTEK]

My iPhone 4 will give me CALL FAILED 50 percent of the time if I am connected to a wifi network.

Connected to 3G, no problems.

This problem was mildly evident in the past month and seems to happen much more with 4.3.

I haven't determined if its just when connected to wifi at home, the phone seems to work fine when acting as a mobile hot spot for me.

Anyone else seen something similar?

very strange, obviously the phone can work for sms and phone calls even with Data turned off, what does your carrier about this?

Do the usual, turn off for 10 to 15 mins turn back on... take out the sim card leave it out for 15 mins.... do things like that, the normal troubleshooting and see if it gets better.
