Can Clara schedule international calls?

Yes!

Clara will try to schedule the call during work hours for both you and your international contacts (unless you specify otherwise). Use a Standard Codeword to expand your preferred meeting times for international timezones that may pose an timing issue. 

Please note that Clara will not be able to determine if a participant is "international" from their domain or email signature. You will need to tell Clara the the meeting to be setup is for an international group. 

Examples: 

"Clara, please find time for me to chat with Matt (who is in London)."

"Looping in Clara to find a time for this international team to talk."
