International calling can not be implemented through the portal. To enable international calling you need to send an email to
support@callharbor.com. Make sure you include what places you want to be able to call and what users should be allowed to make international calls. Making a call to a international number has an addition price based on the location. Rates can change, so consult the International
Rate Table, this is located at the bottom of our main website via a link.
