iPhone calling from Mac not working

I have a similar problem – but only with one Mac. That is, making a call using my iPhone works very well from my iPad and my MBA – but whenever I try to make a call from my iMac, I get the message "iPhone not available: Your iPhone and Mac must be on the same Wi-Fi network" (my translation from Swedish). But the iMac is on the same Wi-Fi network as the MBA, the iPad and the iPhone – and it works well for connecting the MBA and the iPad for making phone calls. The problem must therefore lie with the iMac. I have tried everything that has been suggested here: checking/unchecking/checking all relevant boxes, making sure the same iCloud ID is used, etc. In fact, when I go to FaceTime > Settings, they look identical between my iMac and the MBA, and still I can only make calls from the latter. Any idea what the problem might be? (Naturally, the iMac uses Yosemite.)

Check your ip address and subnet mask settings. While you may be on the same network (ssid), you can still be on a different subnet or the first 3 octets of your ip address are not right. I posted a solution that worked for me as I had the same problem you had. look up a few posts ^^^. In my case my router was giving me a DMZ/public ip address instead of a local one.

Thanks. I noticed that the IP numbers were slightly different at the very end: 10.X.X.2 on my iMac and 10.X.X.40 on my iPhone (the rest was the same). I tried to write the iMac number on the iPhone, using Static, but this did not turn out to work. (The MBA, which works with the iPhone, had yet another number at the end, 10.X.X.6).

you're good then. the first 3 numbers NEED to be the same. the last one MUST be different so they don't cause problems on your network. Is the subnetmask the same? 255.255.255.0 ?

Is the subnetmask the same? 255.255.255.0 ?

Yes.

Yes.

Ok.. well then I got nothing. If you have a device still under applecare use that serial number to call them. Be adamant as they will try to blow you off and say its not their problem but the technology isn't that hard... bluetooth on and working. wifi on and configured. FaceTime signed in and working... they'll go through the steps and possibly something will work.

Good Luck

I have this same problem but in reverse. (iMac works, MBA doesn't). frank from madera posted "Check your ip address and subnet mask settings.

They are both on the same subnet 192.168.3.1 255.255.255.0 iphone is .11 and MBA is .8, iMac is .44. I can ping the iphone from each. If I turn off Facetime/iPhone Cellular Calls, the iMac notes the phone is not configured. The MBA just says to connect each to the same network. BTW, the iMac is connected via wired ethernet so all the business about needing WiFi is misleading.

Tried it on another wireless network MBA 192.168.1.64, iPhone 192.168.1.35 255.255.255.0, def rtr: 192.168.1.1. I can ping the iPhone from the MBA. Inbound call, no problem, Outbound call - no dice. This seems like it is not the connectivity issue that Facetime is reporting on fail of the outbound call.

I can't even do that...there is no such option in my FaceTime prefs...

I have everything set up as recommended. Yosemite, iOS 8.1, same wifi network (same subnet, etc), iPhone 5 with "iPhone cellular calls" enabled with no option on the iMac for the same. Doesn't work.

what model of mac do you have?

My pref window looks different than yours.

FOUND IT!!! - be sure to go to System Preferences/Security & Privacy/Firewall Options and make sure the "Block all incoming connections" is NOT checked.

(The other two are fine.) I use this setting for sitting on open internet and forget to turn it off when home or behind a firewall.

It seems counterintuitive that making a call from the Mac to/through the iPhone would need an INbound connection, but apparently...

One more time too: The Ethernet/WiFi connection doesn't matter. Your Mac only needs to be connected to the same IP subnet as the iPhone through whatever convoluted combination of Ethernet and WiFi access points and technologies. WiFi is NOT a must, any Ethernet connectivity will do (although WiFi is more or less necessary to/from the iPhone :-). e.g., I have tested a MBA connected through Belkin Thunderbolt Dock w/Broadcom GigE - Netgear GigE switch - Airport Extreme 802.11a/5Ghz Wifi - iPhone 5s. Also iPad on 802.11n/2.4Ghz WiFi (SSID#2) Airport Express (bridge mode) WAN port, connected via 100Mb Netgear Ethernet switch and GigE Netgear switch to LAN port on Airport Extreme 802.11a/5GHz (SSID#1) to iPhone 5s).

Apple could possibly make the error message more specific than "make sure the two are on the same WiFi network".

One other thing: Many are saying you MUST US THE SAME APPLE ID... not exactly. I believe you CAN use the Alternate Apple ID that you can configure in Manage Apple ID. Would be good for someone to test and/or confirm this.

See my post below starting "FOUND IT!!!" Hope it helps.

Thats good to know... good work man..

Thanks!

So now that I can make a call I immediately ran into another problem.

See When iPhone calling from Mac, how do I get a touch tone keypad?

Not so sure we can work through this one though.

There isn't a dailpad as of yet (huge oversight), so the way to do it is to open FaceTime and type into the search field the phone number and then click on the phone icon next to it.
