How do Agents Login?

I am currently using asterisk now to setup a helpdesk scenario. I have agents and queues setup, but don’t know how to log a user into the system. In console mode it says that there are two agents not logged in.

My question is, how does a user login to asterisk? Is there a default number that they dial?

Thanks.

you need to make an extension for agentlogin() or agentcallbacklogin(). try show application agentcallbacklogin at the CLI
