Initial Configuration:

To configure this feature, the IMG must have an initial configuration on it. Before proceeding verify that ClientView has an initial configuration on it. The Logical Node, Physical Node, and Facilities including IP bearer spans must already be configured to proceed. Verify all initial configuring has been accomplished before proceeding. When configuring the MWI feature with SS7 Redundancy, verify you select the SS7 Primary node when configuring the SS7 Stack.

Configure Incoming SIP for Message Waiting Indicator:

Configure SIP SGP Profile

Configure a SIP Gateway Profile that allows the Notify message to be sent without a Subscribe message.

Under the Profiles Object in ClientView select New SIP SGP and the SIP Gateway Profile pane will get created.
Under the 'Allow NOTIFY w/o Subscription' select Allow from the drop down menu. See screen capture below.
Under the Dialogic IMG EMS object in ClientView, right click and select New External Network Elements and the External Network Elements Pane gets created. See IMG 1010 - External Network Elements for more information on configuring this pane
Right Click on the External Network Elements Pane and select New External Gateways. A External Gateways Pane gets created. See IMG 1010 - External Gateways for more information on configuring this pane.
Right Click on the External Gateways Pane and select New External Gateway. An External Gateway Pane gets created. Enter the following:
- Name for this Gateway in the Name Field
- Select SIP from drop down menu in the 'Gateway Signaling Protocol' field.
- Select either Gateway IP address or Gateway Host-name and enter IP address or host-name in appropriate fields.
- Select the profile created above from the list of profiles in drop down menu of the 'SIP Profile' field. See Below
  
  See IMG 1010 - External Gateway for more information on configuring this pane.
Under Dialogic IMG EMS, select New Routing Configuration and the Routing Configuration Pane gets created. See IMG 1010 - Routing Configuration Object for more information on configuring this pane
Right Click on the Routing Configuration Object and select New Channel Groups. See IMG 1010 - Channel Groups for more information on configuring this pane.
Right Click on Channel Groups pane and select New Channel Group. A Channel Group Pane appears. Enter the following:
- Name for this Channel Group
- Select SIP from drop down menu in the Signaling Type field.
  Refer to the IMG 1010 - Channel Group topic for more information on configuring the rest of this pane.
Right Click on the Channel Group Pane and select New IP Network Element. An IP Network Element Pane gets created. Select from a drop down menu in the 'IP Network Element' field the gateway that was configured above.
At this point, the Incoming SIP side of the configuration is complete. Follow instructions below to configure the outgoing SS7 side.

Configure SS7 Stack

An SS7 stack must be configured.

Right Click on the Physical IMG object in the object tree of ClientView and select New Signaling. A Signaling Pane will get created.
Right Click on the Signaling object just created and select New SS7. An SS7 StandAlone object will get created. See IMG 1010 - SS7 Signaling Object for more information on configuring this pane.
- Right Click on the SS7 StandAlone object created and select New SS7 Stack. An SS7 Stack Pane will get created. Enter the information needed for your specific network. The first part of configuring the IMG for MWI is to enable SCCP and TCAP signaling in the stack. Select ANSI from drop down menu of both the SCCP and TCAP fields. Feature 1580 is not supported in ITU, only ANSI. See screen capture below.
  
  See IMG 1010 - SS7 Stack for more information on configuring the individual fields of the SS7 Stack Pane.

If configuring a service such as CNAM or MWI on multiple IMG nodes, the SS7 Stack ID's cannot be configured with the same ID. For example, when configuring an IMG Node 0 with stack ID's 0 and 1 then any other IMG Nodes configured under any Logical Node can not have any of the stacks configured with the same ID's (0 or 1). By doing so, the TCAP services cannot be configured.

Right Click on SS7 Stack and select New SS7 Link Set. Enter an Adjacent Point Code. See IMG 1010 - SS7 Link Set for more information on configuring the Link Set.
Right Click on SS7 Link Set and select New SS7 Link. Using drop down menus, enter an Interface - Offset, Channel, SLC and any other information regarding the SS7 Link. Select See IMG 1010 - SS7 Link for more information on configuring the SS7 Link.
Right Click on SS7 Link Set and select New SS7 Route. Enter the DPC. See IMG 1010 - SS7 Route for more information on configuring the SS7 Route.
Right Click on the SS7 Stack Object created above and select New SCCP/TCAP and the SCCP/TCAP pane gets created. No configuration is done within this pane. This pane will allow you to configure other objects that have to do with SCCP/TCAP. See IMG 1010 - SCCP/TCAP link for more information on this pane.
Right Click on the SCCP/TCAP object and select New Subsystem Number. Select a Subsystem Number from the drop down menu.
The Subsystem Number Status is by default set to 'Prohibited'. Using the buttons just below the Subsystem Pane, hit 'Allow' and the status will change to 'Allowed'. See IMG 1010 - Subsystem Number for more information on configuration of the Subsystem Number Pane.
Right Click on Subsystem Number and select New Adjacent Translator. Select from drop down menu the Adjacent Point Code that will be used for the Message Waiting Indicator. The point codes in drop down menu are point codes from the DPC of the Route ID. See IMG 1010 - Adjacent Translator for more information

Configure GCL Services for SIP to TCAP Interworking

Right Click on the Logical IMG Object and select New GCL Services. See IMG 1010 - GCL Services for more information.
Right Click on GCL Services object and select New SIP-TCAP MWI (Interworking). In the Subsystem field select from drop down menu the stack that was created earlier. See screen capture below. For more information on the SIP-TCAP MWI (Interworking) object, see IMG 1010 - SIP - TCAP MWI
Once the GCL Service has been created, the new service can be added to the SIP Channel Group created above. Right Click on the SIP Channel Group created above and select New Service.
Select from drop down menu the service that will be associated with this channel group. See IMG 1010 - GCL Service link for more information on the 'Service' pane in ClientView. See screen capture below.

Configure SS7 Channel Group

A Channel Group must be configured for the SS7 side. Follow Procedure below to configure the SS7 Channel Group.

Right Click on the Channel Groups Object created above and select New Channel Group. Enter a name for this Channel Group and select SS7 as the signaling type. See IMG 1010 - Channel Group for more information on configuring the Channel Group
Right Click on the Channel Group just created and select New ISUP Group. In the OPC-DPC of the object created, select the correct OPC/DPC form the drop down menu. See screen capture below. The selections below all come from the SS7 Route.
Right Click on the ISUP SS7 Server object and select New Circuits. Select the IMG Name along with the specific span/channels. See IMG 1010 - Circuit Group for more information on configuring the Circuits object.
