CHAPTER 30 CRP Configuration
Mediant 4000 SBC | User's Manual
30 CRP Configuration
This section describes configuration specific to the CRP application.
As CRP has similar functionality to the SBC application, for configuration that is common to the
SBC, which is not covered in this section, see the following SBC sections:
■ Configuring Admission Control
■ Configuring Allowed Audio Coder Groups
■ Configuring Classification Rules
■ Configuring Message Condition Rules
■ Configuring SBC IP-to-IP Routing Rules
■ Configuring SIP Response Codes for Alternative Routing Reasons
■ Configuring IP-to-IP Inbound Manipulations
■ Configuring IP-to-IP Outbound Manipulations
● The main difference in the common configuration between the CRP and SBC
applications is the navigation menu paths to opening these Web configuration
pages. Wherever "SBC" appears in the menu path, for the CRP application it
appears as "CRP".
● If you installed a License Key with the CRP feature and you later want to stop
(disable) working with CRP, you need to purchase (from your AudioCodes sales
representative) a new License Key without CRP and install it, and then delete all
CRP-related configuration (described in this section) or reset the device to factory
default settings.
Configuring Call Survivability Mode
The CRP can be configured to operate in one of the following call survivability modes:
■ Normal (Default): The CRP interworks between the branch users and the IP PBX located at
headquarters. The CRP forwards all requests (such as for registration) from the branch users
to the IP PBX, and routes the calls based on the IP-to-IP routing rules. If communication with
the IP PBX fails (i.e., Emergency mode), it still allows calls between the branch users
themselves. If this fails, it routes the calls to the PSTN (if employed).
