18. (For Sylantro/BroadWorks servers) The "ACD Subscription Period" field is enabled by
default with a value of 3600 seconds.
This feature sets the time period, in seconds, that the IP phone re-subscribes the BLF
subscription service after a software/firmware upgrade or after a reboot of the IP phone.
For information about setting the "ACD Subscription Period", see Chapter 5, the section,
"ACD Subscription Period"
19. The "BLA Subscription Period" field is enabled by default with a value of 300 seconds.
This feature sets the amount of time, in seconds, that the phone waits to receive a BLA
subscribe message from the server. If you specify zero (0), the phone uses the value
specified for the BLA expiration in the subscribe message received from the server. If no
value is specified, the phone uses the default value of 300 seconds.
For information about setting the "BLA Subscription Period", see Chapter 5, the section,
"BLA Subscription Period"
20. (For BroadSoft Servers) The "Blacklist Duration" field is enabled by default with a value
of 300 seconds (5 minutes). Valid values are 0 to 9999999.
This feature specifies the length of time, in seconds, that a failed server remains on the
server blacklist. The IP phone avoids sending a SIP message to a failed server (if another
server is available) for this amount of time.
Note: The value of "0" disables the blacklist feature.

on

23. Enable the "Whitelist Proxy" field by checking the check box.
(Disable this field by unchecking the check box. Default is disabled).
When this feature is enabled, an IP phone accepts call requests from a trusted proxy server
only. The IP phone rejects any call requests from an untrusted proxy server.
For information about setting the "Whitelist Proxy", see Chapter 6, the section,
on .
Proxy" page 6-18
24. Enable the "XML SIP Notify" field by checking the check box.
(Disable this field by unchecking the check box. Default is disabled).
Enabling this parameter allows the phone to accept or reject an aastra-xml SIP NOTIFY
message.
Note: To ensure the SIP NOTIFY is coming from a trusted source, it is recommended
that you enable the Whitelist feature (Whitelist Proxy parameter) on the IP phone.
If enabled, and the phone receives a SIP NOTIFY from a server that is NOT on the
whitelist (i.e. untrusted server), the phone rejects the message.
