Is SRST
Secure?
|
After you
verify that the SRST-enabled gateway contains a selfsigned certificate, check
this check box.
After you
configure the SRST and reset the gateway and dependent phones, the Cisco CTL
Provider service authenticates to the Certificate Provider service on the
SRST-enabled gateway. The Cisco CTL client retrieves the certificate from the
SRST-enabled gateway and stores the certificate in the
Cisco Unified Communications
Manager database.
Tip
|
To remove the SRST certificate from the database and phone,
uncheck this check box, click Save, and reset the dependent phones.
|
|
SRST
Certificate Provider Port
|
This port
monitors requests for the Certificate Provider service on the SRST-enabled
gateway.
Cisco Unified Communications
Manager uses this port to retrieve the certificate from the
SRST-enabled gateway. The Cisco SRST Certificate Provider default port equals
2445.
After you
configure this port on the SRST-enabled gateway, enter the port number in this
field.
Tip
|
You may need to configure a different port number if the port is
currently used or if you use a firewall and you cannot use the port within the
firewall.
|
|
Update
Certificate
|
Tip
|
This
button displays only after you check the Is SRST Secure? check box and click
Save.
|
After you
click this button, the Cisco CTL client replaces the existing SRST-enabled
gateway certificate that is stored in the
Cisco Unified Communications
Manager database, if a certificate exists in the database. After you
reset the dependent phones, the TFTP server sends the cnf.xml file (with the
new SRST-enabled gateway certificate) to the phones.
