Blacklist Duration
The Blacklist Duration feature helps to reduce unnecessary delays during proxy/registrar server failures, caused by the
BluStar 8000i repeatedly sending SIP messages to a failed server. If you enable this feature, whenever the BluStar 8000i
sends a SIP message to a server and does not get a response, the BluStar 8000i automatically adds the server to the
blacklist. The BluStar 8000i avoids sending messages to any servers on the blacklist. If all servers are on the blacklist, then
the BluStar 8000i attempts to send the message to the first server on the list.
You can specify how long failed servers remain on the blacklist in the BluStar 8000i’s configuration file. The default set-
ting is ‘300’ seconds (5 minutes). If you set the duration to ‘0’ seconds, then you disable the blacklist feature.
Configuring Blacklist Duration Using the Configuration Files
Use the following procedure to configure the blacklist duration:
Whitelist Proxy
To protect your BluStar 8000i network, you can configure a Whitelist Proxy feature that screens incoming call requests
received by the BluStar 8000i. When this feature is enabled, an BluStar 8000i accepts call requests from a trusted proxy
server
only . The BluStar 8000i rejects any call requests from an untrusted proxy server
Configuring Whitelist Proxy Using the Configuration Files
Use the following procedure to configure the whitelist proxy feature:
XML SIP Notify Events
In order for an XML push to bypass the NAT/firewall, the BluStar 8000i supports a proprietary SIP NOTIFY event (aastra-
xml) with or without XML content. An administrator can enable/disable the SIP NOTIFY event using the “
sip xml notify
event ” parameter.
If XML content is provided in the SIP NOTIFY, it is processed directly by the BluStar 8000i as it is done for an XML PUSH. If
the content is empty in the SIP NOTIFY, the BluStar 8000i automatically triggers a new pre-configured action uri (action
uri xml sip notify).
