220 Nortel IP Softphone 2050
Licenses
The IP Softphone 2050 Release 3.0 requires a license to operate. If the
phone cannot obtain a license from one of the licensing schemes then it
cannot connect to a Call Server and an error message appears on the
phone screen.
While the IP Softphone 2050 runs, it first goes through three licensing
schemes before it connects to Call Server. After the phone obtains a
license, it repeats the procedure at a random interval. If the licensing
scheme fails then the IP Softphone 2050 disconnects from the Call Server
unless you are on an active call, in which case the phone does not
disconnect until the call ends.
The licensing schemes are as follows:
• “Check out license” (page 220)
• “Cached license” (page 220)
•
“Evaluation period ” (page 220)
Check out license
The IP Softphone 2050 tries to obtain or checkout a license from a License
Server. These licenses are stored on a License Server machine located
on your network. For information about how to install and configure a
Licensing Server, see “Provisioning a License Server” (page 223). After
a client successfully checks out a license from the License Server a
heartbeat mechanism activates to validate the license every 2 minutes. If
the heartbeat is lost then the client attempts to reconnect to the server 5
times before it loses the checked out license.
Cached license
After the IP Softphone 2050 successfully checks out a license from the
License Server, it records the license details in a secure location. You can
refer to this license as a backup license. The cached license is available
for 5 days.
Evaluation period
After you install the IP Softphone 2050, it can run without a license for a
period of 30 days. After the expiration date passes, you must run the IP
Softphone 2050 Settings tool to specify a License Server. Otherwise, the
phone cannot connect to the Call Server.
