Setting up telephone prefixes

Before configuring a remote Octel Analog Networking node, you need to set up telephone prefixes. The telephone prefix is the dialing code required by the PBX to access a remote Octel Analog Networking node, for example, 91, where 9 is the code for external calls and 1 is required to dial long distance. You may also need to include the international dialing code, for example 9011, if your Octel Analog Networking node is located in the United States and the remote Octel Analog Networking node is located outside the United States.

Phone prefixes are maintained separately from the telephone number used to call the node, known as the access telephone number. This makes it easy to change a telephone prefix without having to modify the details of every node that uses it. You can enter the access telephone number on the Nodes tab. For more information, see Configuring access telephone numbers.

To create a telephone prefix:

Start Octel Analog Networking Gateway Administration.

For more information, see Starting Octel Analog Networking gateway administration.

Click the Phone Prefixes tab.

Click Create.

The system displays the Create Phone Prefix dialog box.

In the Name field, enter a textual description of the telephone prefix, for example, the name of the city or country.

In the Number field, enter the telephone prefix number. Include the international dialing code if required.

Note: You may need to specify a code for an outside line, for example, 91, where 9 is the code for external calls. Do not use dashes (–) to separate digits. You may be required to enter a comma between digits to represent a pause in dialing, for example, 9,1.

Click OK.

To modify a telephone prefix:

From the telephone prefix list on the Phone Prefixes tab, select the prefix you want to modify.
