"Call failed" with FaceTime audio

I resolved this issue by switching to the exact same wifi wireless frequency. Most modern routers have two frequencies, 2.5ghz and 5ghz, with there being two different SSIDs for these frequencies. Make sure you are on the same subnet (same router) and on the same frequency.

Background:

- unable to call using Face Time application on macOS 10.13.1

- receive error "call failed"

Resolution: Verified that the time on both devices (iPhone and MacBook Pro) are set to automatic. Then changed my network to the same frequency. My MacBook Pro was using the 5ghz while my iPhone was using the 2.5ghz. After change my iPhone to use the 5ghz, everything worked.

I'm having this exact same issue. New MacBook Pro. Wireless is on my 5ghz network and wired is on the same network subnet as the wireless and my iPhone X. iPhone X is also set to 5ghz network. Date and Time on both the iPhone and MacBook Pro are set to automatic. I can make audio calls through FaceTime without a problem, but with both network adapters active I cannot receive audio calls on my MacBook Pro. The funny thing is that if someone FaceTime video calls me, I receive those just fine.

I don't remember having this issue with my iMac on the same OS as my new MacBook Pro. So in summary:

1. iPhone X and MacBook Pro are on the same network, subnet, and frequency (5ghz).

2. iPhone X and MacBook Pro have date and time set to automatic.

3. Inbound/Outbound FaceTime Video calls work fine on both devices.

4. Outbound FaceTime Audio calls on MacBook Pro works fine.

5. Inbound FaceTime Audio calls on MacBook Pro fail. MacBook shows the incoming call but when "answer" is clicked it sits for a moment and then disconnects with "Call Failed". iPhone X also shows a "Call Failed" error.

If I turn off the wireless, everything works fine. Sounds like a routing problem within the FaceTime software on where to send responses when you click "answer" on the incoming call on the MacBook.

I am having the same problem and also have experienced this since the last update. I am able to make FaceTime calls from my IMAC, but all audio calls received ring through, but fail when I try to accept.

This issue just surfaced for me to day (10/10/17) and I've tried everything above but nothing's working. Are there any alternative fixes that haven't been mentioned recently? Thx!

I am having same issue since I did the latest update. I have checked everything out there and can’t seem to get it to work. Any luck?

This was exactly my problem!

Me to same stuff

I resolved this issue by turning _off_ my automatic VPN.

VPN on: FaceTime unable to access my phone

VPN off: FaceTime completes the call.

Just in case someone finds this question and does indeed have a VPN up and running.

I realize this is an old thread and perhaps no longer an issue, but I found that if I am hardwired and have my wireless enabled at the same time... the call fails. If I disable the wireless, it works fine.

The following fix worked for me: on the Mac, launch the FaceTime app and then select FaceTime | Turn FaceTime Off. Then turn it back on, and login by clicking the Turn On button in the FaceTime window. This operation will refresh your login via AppleID.

Hello AnAnonymousUser!

FaceTime and FaceTime audio are certainly helpful and I like being able to use both on my devices to stay in touch. We can check things out and see what's going on.

Let's check a few settings on both. Settings > General > Date & Time on the iPhone to make sure Set Automatically is on. Similar place on the Mac is in System Preferences > Date & Time and confirm that Set date & time automatically is checked. You may have to unlock the window in the bottom left corner to let you do check that box if it's unchecked.

After checking those, restart both devices and make a test call or try receiving one, please.

For the Mac:  > Restart

For the iPhone: Restart your iPhone, iPad, or iPod touch - Apple Support

Let us know how that goes. Regards.

Thanks for following up!

On the Mac, let's try starting to safe mode and trying again and then try again in a new user account on the computer.

On the iPhone, if it's on Wi-Fi, let's turn off Wi-Fi in Settings and test on Cellular or vice versa.

If both give the same failed message, then we may want to go through our website to contact us for additional steps: Apple - Support - Product Selection

Best wishes.

I have had the SAME exact issue and it is driving me nuts.

Did you get it to work?

Apple broke something recently.

Adding: If I enable both ends to "allow calls even when device isn't nearby" (guessing it goes through the internet/iCloud) instead of just over wifi, it does work about 85 percent of the time although of ten the voice on the other end sounds like micky mouse. PLEASE, I hope SOMEONE has figured this out.
