SIP–DECT OM System Manual Release 3.0 6 Licensing
Aastra depl-1624/1.0 Page: 42 (241)
During purchase of a license file from the Aastra license server, the MAC address of 3 RFPs
must be entered. These 3 validation RFPs are used to operate the grace period as described
in section 6.1.1.
When obtaining the license file from the Aastra license server, it is possible to use the PARK
used for a small or medium system installation. This prevents the need to re-subscribe all
handsets.
Note: Note: When once changed via activation file upload, the PARK cannot be changed
any more on the
System settings page of the OM Web service.
