Each new license includes one year of free maintenance. Maintenance requires correct
end-user details otherwise it will not be activated.
A maintenance package entitles you to free updates of 3CX Phone System, including
patches, 3CX tested IP Phone firmware updates,
3CXPhone client updates and of course any new versions that are released.
Late maintenance renewal is not available, a 90 days grace period is given after
which users can easily switch to an annual licence.
Version upgrades are replaced with Annual licence keys. Users can upgrade from an
old version to the latest version and get an annual licence key free
