Configuring SIP trunk

A SIP trunk is used to create a virtual communication channel between two SIP servers. It can be two Intellect SIP servers, or the Intellect SIP server and a third-party SIP server.

Before you start configuring the SIP trunk, it is necessary to add to Intellect the SIP-devices of a third-party server based on the same SIP-terminal on which the SIP trunk will be added (see Configuring SIP-devices of the Intellect's SIP server).

In the following description of the SIP trunk configuration procedure, the connection between the Intellect SIP server and a third-party SIP server is used as an example.

The SIP trunk is configured as follows:

1. Create a SIP trunk object on the basis of the SIP-terminal object which is to be connected with the SIP trunk (1).
   
2. On the Connection settings tab, in the Incoming connection settings group:
   1. In the Trunk ID field (2), specify the ID of the third-party SIP server that is registered in Intellect;
   2. In the Password field (3), enter the password for connecting to a third-party SIP server;
   3. The State field (4) displays the current status of the registered SIP server.
3. On the Connection settings tab, in the Outgoing connection settings group:
   1. In the Trunk ID field (5), specify the ID of the Intellect SIP server, which is registered on a third-party SIP server;
   2. In the IP address field (6), enter the IP address of the third-party SIP server;
   3. In the Port field (7), specify the port of the Intellect SIP server;
   4. In the Password field (8) specify the password for connecting to the Intellect SIP server;
   5. The State field (9) displays the current status of the Intellect SIP server.
4. On the Devices tab, select the devices of the third-party SIP server that will be used on the Intellect SIP server:
   1. From the Subscriber drop-down list (10), select the device number;
      
   2. The Name (11) and Subscriber type (12) fields will display the device name and type, respectively;
   3. In the Use column (13), put * (asterix) in front of the devices that will be used.
5. Click the Apply button.
