Configuring SIP

The SIP Configuration procedure configures a SIP signaling stack, a SIP channel group, and connects to an external SIP gateway. The procedure describes the basic configuration needed to accept a call coming from a network utilizing SIP as its signaling protocol. Below is a Quick Start diagram displaying the objects. In addition, the objects in blue link to topics that describe other SIP functionality that is not needed in a basic SIP configuration.

Configure SIP Signaling Gateway Profile (SGP)

When communicating with an external gateway there are various attributes/features that need to be associated with that particular gateway. Within the SIP Signaling Gateway Profile object the attributes/features can be configured and then associated with SIP Signaling object, the External SIP Gateways object and External ENUM Server Sets object. The SIP Signaling Gateway Profiles configured will all be selectable from a drop down menu in each of the objects described above.

Note: Before proceeding, verify that the Basic Configurations topic has been achieved. The Basic Configurations topic sets up objects such as VoIP Interfaces and IP Bearer ports needed prior to starting the Configuring SIP procedure.

 

  1. Right Click on the Profiles object and select New SIP SGP. A default SIP Signaling Gateway Profile is created. This profile which has a default ID of ID:0 cannot be modified. It is a generic SGP. To modify the individual fields, change the SIP Profile ID from ID:0 to a number other than zero. The individual fields can now be modified. Multiple SGP objects can be created. For more information refer to SIP Signaling Gateway Profile (SGP).

Configure SIP Signaling Stack

Configure the SIP Signaling stack that will be used by 2020 IMG. The SIP stack must be created for each Physical 2020 IMG.

  1. Right click on the IMG Name object and select New Signaling. In the Signaling object that appears, there is no configuration needed. Refer to the Signaling topic for more information on this topic.

  2. Right click on the Signaling object and select New SIP. A SIP signaling object gets created. The SIP Signaling IP address automatically takes the IP address of the CTRL port on rear of 2020 IMG. This can be changed as needed.

  3. Select from drop down menu in the Remote IMG's SIP Profile field one of the SIP SGP configured under the Configure SIP Signaling Gateway Profile section above. Refer to SIP Signaling for more information regarding this topic.

Configure External Gateway

  1. Right Click on IMG EMS and select New External Network Elements. The External Network Elements object is a container object and no configuration is needed here. For more information on this object refer to the External Network Elements topic.

  2. Right Click on External Network Elements and select New External Gateways. The External Gateways object is a container object and no configuration is needed here. For more information on this object refer to the External Gateways topic.

  3. Right Click on External Gateways and select New External Gateway. Enter a name that identifies this gateway.

  4. Select SIP from drop down menu in Gateway Signaling Protocol field.

  5. Select either Gateway IP Address or Gateway Host name from Gateway Address Type field. In this procedure the IP Address will be how the 2020 IMG will communicate with external gateway.

  6. Enter the IP address of the external gateway in the Gateway IP Address field.

  7. Select the SIP Profile from SIP Profile field drop down menu. For more information on configuring the External Gateway object, refer to the External Gateway topic.

Configure Channel Group and External Network Element

Configure a SIP Channel Group. The SIP channel group will communicate with an external SIP gateway. After configuring the external gateway, configure the external network element the channel group will communicate with.

  1. Right Click on the IMG EMS object and select New Routing Configuration. The Routing Configuration object is a container object and no configuration is needed here. For more information on this object refer to the Routing Configuration topic.

  2. Right Click on the Routing Configuration object and select New Channel Groups. The Channel Groups object is a container object for multiple channel groups. No configuration is needed here. For more information refer to Channel Groups topic.

  3. Right click on the Channel Groups object and select New Channel Group. In the Name field, enter a name for the Channel Group being configured.

  4. Select SIP from the drop down menu in the Signaling Type field.

  5. Select the Incoming and Outgoing IP Profile from drop down menu. For more information on configuring the Channel group object, refer to the Channel Group topic.

  6. Right Click on the SIP Channel Group and select New IP Network Element. Select from drop down menu the gateway configured in Configure External Gateway section above.
