Here’s what I did.

  1. Signed out of Gmail.
  2. Fired up my favorite VPN client and got myself a US IP address.
  3. Signed back into Gmail, and found a nice “Call Phone” option in the chat column. It worked for me so I am assuming it should work for many others out there. Try it out and let me know if it does. Also, it should be noted that as soon as I disconnected from the VPN and came back to my original connection, the call phone option was gone. So this isn’t a permanent thing and would require you to stay connected using the VPN.
