IMG 1010 - RADIUS - Diversion info in CDR

In software build 10.5.3 the word Cantata in each of the Vendor Specific Attributes (VSA) has been replaced with the word Dialogic. All VSA names prior to software 10.5.3 will have Cantata in the name and all VSAs from software 10.5.3 and beyond will have Dialogic in the name.

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.dialogic file will get loaded into the /opt/dialogic/common/radius directory. If using FreeRadius, the newest dictionary.dialogic 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:

• The first Diversion Header maps to Dialogic-sip-top-diversion which is the Redirecting number.

• The second Diversion Header maps to Dialogic-sip-bottom-diversion which is the Original Called Number

• In this example, the IMG 1010 - ISDN Interworking Redirection pane was configured as a default setting of 'Redirecting'.

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.

• Dialogic-original-called-number

• Dialogic-redirecting-number
  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:

• There are more than two Diversion Headers coming from SIP leg. In this case the Radius CDR log will display only the top and bottom Diversion Headers.

• The IMG can be configured to interwork only the Original Called number. In the Original Called case, the Radius CDR log would output only the OCN. See IMG 1010 - ISDN Interworking Redirection
  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.
