The SIP to SIP-T Interworking object was created to allow the IMG 2020 to accept a SIP message from a SIP endpoint which originally had no SIP-T information in it and create a SIP-T message which has the ISUP information embedded in its SIP message body. This information is then sent to an endpoint that accepts SIP-T messaging. The information below will explain how to configure the IMG 2020 to accept the incoming SIP message and send it out a SIP-T message.
When creating the SIP Profile SGP, the default ID which is ID:0 disables SIP to SIP-T Interworking. In this state the SIP to SIP-T Interworking object cannot be modified. To allow the SIP to SIP-T Interworking object to be utilized, the Default ID in the SIP Profile (SGP) object must be changed to any ID other than ID:0. If the SIP Profile (SGP) object had already been created using ID:0, the object must first be deleted and then recreated using a different ID.

One SIP to SIP-T Interworking object per SIP Profile (SGP) object.

To configure this object the following objects must be created first. First an SS7 stack must be created. Next, configure the SIP Signaling object and modify the Enable SIP-T field to Yes. Once the SIP-T is enabled then a SIP-T entity object can be created under the SIP signaling object. At this point the stack and variant can be configured. Once these initial objects have been completed the SIP to SIP-T Interworking object can be created under the SIP SGP. Lastly the SIP SGP can be input into an External Gateway object. For more in depth procedure on how to configure, see Configuring Interworking between SIP and SIP-T below.
Configure SIP to SIP-T InterworkingÂ
Field Descriptions
SIP To SIP-T Interworking: (Disabled - Default)
Select from a drop down menu whether the SIP to SIP-T Interworking is Disabled or Enabled.
Disabled (Default)Â - When Disabled is selected, the SIP to SIP-T Interworking feature is disabled.
Enabled - When enabled is selected, the SIP to SIP-T Interworking object can now be edited for use.
Before enabling this field, the SIP-T Entity object under the SIP Signaling stack must be configured.
SIP-T Entity
When SIP To SIP-T Interworking field above is enabled, the SIP-T Entity field will display a drop down menu which includes all the SIP-T Entities that have been created under the SIP Signaling object. Select the SIP-T Entity from drop down list.
For each of the ISUP Parameters described below the individual fields are initially filled-in with f 's. A field that has all f 's in it will send a Default value for that parameter. Each parameter explained below will have a link below it. The links refer to a table which includes values for that parameter (binary form). Where applicable the Default value is marked in red text. If the default value marked in red is not going to be inter-worked, the user must enter a hex value corresponding to the value that will be usedÂ
IAM - Nature Of Connection Indicators
The Nature of Connection Indicator is sent in the forward direction to provide information regarding the circuit connection specified in the CIC parameter of the message. This message is one byte. Click on the following link to display a table of the Nature of Connection Indicators. Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will inter-work when feature is enabled.
Nature of Connection Indicators Table (SIP to SIP-T Interworking)Â
IAM - Forward Call Indicators
Contains information that specifies both the preferences about the call setup in the forward direction and the conditions encountered so far in setting up the call. This message is two bytes. Click on the following link to display a table of the Forward Call Indicators (Octets 1 and 2). Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will inter-work when feature is enabled.

IAM - Calling Party Category
Information sent in the forward direction indicating the category of the calling party and, in case of semi-automatic calls, the service language to be spoken by the incoming, delay and assistance operators. Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will Interwork when feature is enabled.
Calling Party Category Table (SIP to SIP-T Interworking)Â
IAM - Transmission Medium Requirement
The transmission medium used in call setup is sent in the backward direction in the event that the original circuit requested could not be used. This parameter then identifies the circuit type and is carried in the ANM, ACM, and CPG messages. Click on the following link to display a table of the Transmission Medium Requirements Table (Octets 1 and 2). Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will Interwork when feature is enabled.
Transmission Medium Requirement TableÂ
IAM - User Service Information
Used when the subscriber is requesting data transmission on the voice facility without the use of a modem. Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will Interwork when feature is enabled.
User Service Information TableÂ
ACM - Backward Call Indicators
Sent in the backward direction to indicate that the remote end of a trunk circuit has been reserved. Information relating to the characteristics of the connection, signaling path and called party are sent in the backward direction. Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will Interwork when feature is enabled.
Backward Call Indicators Table (SIP to SIP-T Interworking)Â
CON - Backward Call Indicators
Sent in the backward direction to indicate that the remote end of a trunk circuit has been reserved. Information relating to the characteristics of the connection, signaling path and called party are sent in the backward direction. Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will Interwork when feature is enabled.
Backward Call Indicators Table (SIP to SIP-T Interworking)Â
CPG - Event Information
Information indicating the type of event which caused a call progress message to be sent. Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will Interwork when the feature is enabled.
Event Information Table (SIP to SIP-T Interworking)Â
REL - Cause Indicators
Information sent in either direction indicating the reason for sending the message (e.g. release message). Where applicable, the default values are displayed in red. These are the default values that the IMG 2020 will Interwork when feature is enabled.
Cause Indicators Table (SIP to SIP-T Interworking)
SIP-T MIME To SIP Interworking
Enable the SIP-T MIME buffer interworking to SIP the same way IMG2020 does for SS7 to SIP interworking.
