Note: The connection to the IP-PBX will only be established after the certificate is
acknowledged.
If the certificate expires, the ongoing connection is maintained but it will not be possible
to start a new connection until the certificate is renewed.
To add a certificate to the trust list do the following:
1 Select General > Certificates.
2 In the Rejected certificates section select the check box of the certificate you want
to trust.
3 Click "Trust".
To ensure two-way authentication the IP-PBX also downloads a certificate from the IPBS.
The trust list must also be manually updated with this certificate in the IP-PBX similarly to
the IPBS.
For more information about certificate handling, see 8.1.10 Certificates on page 73.
8.5.17 Registration for Anonymous Devices
Handsets registered anonymously can make emergency calls through an extension
reserved for anonymous users.
Note: Call restrictions must be configured in the PBX to allow for emergency calls only.
This option also provides a solution for the case when the Master, running on an IPBS with
local power or an IPBL, loses IP connectivity without the local host Radio losing its
connection to the Master. The handsets locked to this Radio become isolated from the
system without any notification.
1 Select DECT > Master.
2 Enter the registration name and number to the PBX in the Registration Name /
Number text fields.
3 Select the "Deactivate Master if no connection" check box to make the Master
deactivate itself if the anonymous registration to the PBX fails. As a result the local
host Radio will fail to register to the Master, and handsets, depending on their type,
can move to another Radio that is operable.
Note: It is not recommended to use this option for a Master without a Standby Master.
4 Click "OK".
Note: A simpler and reliable way to handle this case is to deactivate the local host Radio on
the Master.
8.5.18 Select Mobility Master Mode
In a system with two or more Masters (Multiple Master system), a Mobility Master must be
configured. For more information on Multiple Master Systems, see the System Planning
documentation for IP-DECT.
1 Select DECT > Mobilty Master.
2 Select in the Mode drop-down list:
• "Active", if this IPBS/IPBL is the Mobility Master.
• "Standby", if this IPBS/IPBL is the Standby Mobility Master.
