Configure Digit Matching and Translation

The topic below displays how to configure the IMG 2020 to match on a specific incoming digit string and translate it. Once translated, send the translated string out an outgoing channel group. The procedure assumes that the configuration described in the Basic Configurations topic have been completed and therefore will start with creating and configuring channel groups. The procedure describes how to match and translate a number received from the SIP side, translate it and transmit it out to another SIP network.

Method to download translation table configuration

A Translation Table and its entries will not automatically be sent to the IMG 2020. Simply committing an object does not download the translation table. After configuring the translation table, translation table entries, and then committing the object, click on the Download Translation Table button and the updated translation table will be sent to the IMG 2020.

Configuration Example

The instructions below describe how to configure the IMG 2020 to match on an incoming digit string and translate it. The procedure assumes that the configuration described in the topic have already been accomplished. The procedure will create two channel groups. One channel group will be considered an incoming channel group which will match the incoming number and translate it to a four digit extension. The second channel group will be an outgoing channel group and the digit string (1) will be pre-pended to the ten digit number dialed.

3. Right click on the Channel Groups object and select New Channel Group. Enter a name to identify this channel group and modify the signaling type to the protocol of the incoming call. In this procedure the channel group was labeled ChGrp_In and will be configured as an SS7_ISUP channel group. Refer to the Channel Group topic for more information on this object.

4. Create a second channel group for outgoing side. In this procedure this channel group was labeled ChGrp_Out and will be configured as a SIP channel group.

5. Open the Incoming Channel Group created earlier (ChGrp_In) and in the Incoming Translation Table field, select the translation table created above.

6. At this point the translation has been configured and routing for the incoming channel group has been completed. 

Create Outgoing Translation Table and associate with Channel Group

1. Right click on Routing Configuration again and select New Outgoing Translation Tables. The Outgoing Translation Tables object is the parent object to multiple translation tables and translation table entries. No configuration is needed in the Outgoing Translation Tables object. Refer to the Outgoing Translation Tables topic for more information on this object

5. Open the Outgoing Channel Group created earlier (ChGrp_Out) and in the Outgoing Translation Table field, select the translation table created above.

6. At this point the configuration has been created but has not been sent to the IMG 2020. Click on the Channel Groups object. This object will have a yellow exclamation point on the icon indicating the configuration has not been sent to the IMG 2020. Click on the Download Resource Tables button and the Channel Group configuration will be sent to the IMG 2020.
