If a tracking number you expected to swap on your website is not swapping, it may be a good idea to check if your swap target is correct.
The swap target is the telephone number CallRail looks for on your website to dynamically replace with a tracking number. By default, the swap target is the destination number, but you can specify a different swap target for each tracking on the number configuration page.
If the number on your website does not match your swap target, your numbers will not swap.
Use our instructions on Swap Targets to verify or change your swap settings.
