Use this window to view and configure mappings between specific, internal (Call Processing Component) cause codes and SIP codes. These cause maps are components of CPC To SIP cause map profiles. The mappings for the default CPC To SIP cause map profiles can be listed in this window, but you cannot modify or delete the cause maps within a default profile. However, you can create new cause maps within a custom cause map profile you have added. Refer to SIP Cause Code Mapping - CPC To SIP Cause Map Profile for information on how to create a custom profile object.

If you choose to base your custom profile on one of the default profiles, any cause maps you create for your custom profile override the mapping specified in the base profile. Otherwise, the custom profile reflects the cause maps of the profile on which it was based. 

To View Cause Maps

On the SBC main screen, go to Configuration > Profile Management > Category: Signaling Profiles > SIP Cause Code Mapping > CPC To SIP Cause Map Profile > Cause Map or
All > Profiles > Signaling > SIP Cause Code Mapping > CPC To SIP Cause Map Profile > Cause Map

The Cause Map window opens. Select a cause map profile in the CPC To SIP Cause Map Profile list to see the cause maps for a specific profile.

To Create a Cause Map

You cannot add new cause maps to any of the default cause map profiles. To create a new cause map for a custom cause map profile you created:

  1. In CPC To SIP Cause Map Profile, select the name of the custom cause map profile to which you want to add the cause map.

  2. Click New Cause Map. The Create New Cause Map window is displayed. 

  3. Use the following table to enter parameters and click Save.
ParameterDescription
CPC CauseSpecifies a CPC cause value. The range allowed is 1 to 255.
SIP CauseSpecifies the SIP status code value to map to the given CPC Cause value. The range allowed in 300 to 606.
Q850ReasonSpecifies the Reason Header Q.850 value to include in the SIP message if the Include Q850Reason option is enabled in the profile. This also determines the cause code value to include in MIME encapsulated ISUP, if the call uses SIP-I signaling. A value of "0" (default) indicates that the Reason Header Q.850 value should be equal to the predefined ISUP mapping associated with the CPC Cause value. If no predefined ISUP mapping exists (as for internal cause codes 151-159), the ISDN mapping is used. The allowed range is 0- 127.

To Edit a Cause Map

You cannot edit the cause maps for the default profiles. To edit a cause map in a custom cause map profile:

  1. Click the radio button next to the specific cause map. The Edit Selected Cause Map window is displayed below.
  2. Make the required changes and click Save.

To Copy a Cause Map

You cannot copy a cause map in a default profile. To copy a cause map from a custom cause map profile to edit and use in the same custom profile:

  1. Click the radio button next to the specific cause map you want to copy.
  2. Click Copy Cause Map. The Copy Selected Cause Map window opens.
  3. Make any required changes and click Save.

To Delete a Cause Map

You cannot delete a cause map in a default profile.To delete a cause map from a custom cause map profile:

  1. Click the radio button next to the specific cause map that you want to delete.
  2. Click the X at the end of the row.
  3. Confirm the deletion when prompted.
