Typically, an agent logs in and out of a call queue from their phone. However, you can manage agents in a call queue from the portal as needed—maybe an agent is not logged in but should be (slacker).
1. Click Call Queues in the left sidebar.
2. Click the call queue that requires an additional agent.
3. From the General tab > Agents Logged Into Queue section, browse for and select the desired agent.
4. Click [SAVE].
