Diversion Support in Radius

Overview:

Feature F-1625 takes the "username" or "string" portion of either a Diversion Header, Redirecting Number, or Original Called Number and adds it to one of the VSA's displayed below. Feature 1625 adds four new Radius VSA's which all have to do with redirecting or forwarding a called number. This feature is being added to software 10.5.1_ER3 and above. The added VSA's are as follows:

 

Dialogic-sip-top-diversion = "username"

Dialogic-sip-bottom-diversion = "username"

Dialogic-original-called-number = 'username"

Dialogic-redirecting-number = "username"

 

This feature was added in 10.5.1 ER3. When installing software 10.5.1 ER3 or newer, the newest dictionary.cantata file will get loaded into the /opt/dialogic/common/radius directory. If using FreeRadius, The newest dictionary.cantata file must then be copied into the /usr/share/freeradius directory.

 

See below for more information on this feature.

 

Example 1:

Incoming -- (SIP to ISDN):

Below is a trace of a Call which is coming into IMG using SIP and eventually going to an ISDN TDM network. The capture displays a portion of  an incoming SIP trace and the corresponding Radius CDR logs. The first Diversion Header which is the topmost header highlighted in red will generate the VSA Dialogic-sip-top-diversion with the redirecting number as the username. The second Diversion Header in the Call Trace will generate the VSA Dialogic-sip-bottom-diversion with the Original Called number as the username.

Notes on above Call Trace:

 

Example 2:

Incoming -- (SS7 to SIP) -- OCN configured in Interworking Redirection pane in ClientView.

Below is a trace of a call which is coming into IMG using SS7 and eventually going to a SIP network. The capture displays a portion of  an incoming SS7 trace and the corresponding Radius CDR logs. In this example, Redirection information from SS7 is included in the Radius VSA's. The Radius CDR Log will show the redirection information from SS7 in the following VSA's.

The new VSA's in the Radius detail file will be displayed on the A-leg (incoming) portion of the call. They will not be displayed on the B-leg (outgoing) portion of the call.

Additional Information:

Below are tables which display how the Radius CDR log would output the newest VSA's. The order of how the VSA's are output can change depending on the following:

Refer to tables below to explaining how the Radius CDR log files are output.

 

On the next few tables, the Incoming side displays the Diversion Header and the order in which they are received. The Radius VSA sent side displays the VSA's sent from IMG and the order in which they are output in the Radius CDR log.
