By default, your Clerk number is SMS Only. If someone tries to call your Clerk number the call will be dropped. We have a number of other add-ons that would allow you to either call forward to a different number or enable full voice capabilities.
Clerk’s “Call Forwarding” add-on allows all the calls you receive on your Clerk number to be forwarded to a number of your choice. Please submit your forwarding request to firstname.lastname@example.org.
