For the correct operation of CounterPath’s desktop and mobile softphone clients, it is necessary that CounterPath’s softphones be able to periodically contact the CounterPath License Server to validate the softphone's license key(s).
For CounterPath softphones that are used from behind a corporate firewall, in cases where there are strict firewall rules in place, the IT administrator must make changes to allow the CounterPath License Server to be contacted.
