• Webex Calling internal extension length can be 2 to 10 digits, with a default of 4. in context
• Webex Calling's 'Allow extension dialing between locations' toggle is on by default and works if extensions are not duplicated across locations. When it is off, extension calls reach a matching extension in the caller's own location. in context
• The Webex Calling location routing prefix length is 1 to 7 digits and includes the steering digit, so a length of 4 leaves 3 digits for the site code. in context
