Release Notes for 3Com Asterisk Appliance Release 1.4.0.14.3 Page 4

Calling Queues

From the Call Queues tab in the 3ComAsteriskGUI, you can create multiple calling queues and

also assign multiple agents as members of those calling queues.

Before you can assign an agent to a calling queue, you must enable the Is Agent field that

corresponds to the agent’s user extension on the Users page.

For agents to receive calls as members of a calling queue, they must first log in to the calling

queue. The Options tab in the 3Com AsteriskGUI lets you choose two methods for agents to log

in to a calling queue. Under the Agent Login Settings section, select one of the following:

Agent Login Extension – When an agent dials this number, the agent is immediately

logged in to all the calling queues of which the agent is a member. The agent will hear hold

music until a telephone call comes in. If the agent hangs up the telephone, the agent is

automatically logged out of all the calling queues.

Agent Callback Login Extension – When an agent dials this number, the agent is logged in

to all the calling queues of which the agent is a member. The agent can leave the telephone

on hook. The telephone will ring when the agent receives a call through any of the calling

queues. Unlike the Agent Login Extension option, the agent remains logged in to the calling

queue until the agent explicitly logs out of the calling queue.

If your agent login setting is Agent Login Extension, to log in to any calling queues from your

telephone:

1Dial the Agent Login Extension.

2At the prompt, enter your extension.

3At the prompt, enter your password.

4Wait for the system to indicate you are logged in as an agent.

The system plays hold music until you receive a call.

To log out of the calling queues, hang up the telephone.

If your agent login setting is Agent Callback Login Extension, to log in to any calling queues from

your telephone:

1Dial the Agent Callback Login Extension.

2At the prompt, enter your extension.

3At the prompt, enter your password.

4At the prompt, enter a new extension. This is the extension of the telephone that you are

currently using, which can be the same as the extension in Step 2 or another extension if you

are at another telephone.

5Wait for the system to indicate you are logged in as an agent.

6Hang up the telephone.

Release Notes for 3Com Asterisk Appliance Release 1.4.0.14.3 Page 5

You can now receive calls made to the calling queues.

To log out of the calling queues:

1Dial the Agent Callback Login Extension.

2At the prompt, enter your extension.

3At the prompt, enter your password.

4At the prompt for a new extension, press #.

5Wait for the system to indicate you are logged out as an agent.

Modifying Configuration Files

If you have opened a configuration (.cfg) file from the Linux shell, make sure that you close the

file before you use the 3Com AsteriskGUI to make changes associated with that configuration

file. If you keep the file open, 3Com Asterisk might not function as expected.

Updating Your 3Com Asterisk Appliance Configuration
