An agent is signed in and shows **Available**, but calls aren't reaching them. ## Quick checks * Is the agent actually a member of the queue or assigned to the campaign you expect? * Are there any calls actually waiting? An idle agent with no callers waiting is expected, not broken. ## Cause: not a member of the queue **How to check:** Open the queue in **Queues** and confirm the agent is listed as a member. **How to fix:** Add them — see [Add queue members and skills](/inbound/queue-membership-and-skills). ## Cause: campaign assignment is Selectable, and the agent hasn't opted in **How to check:** Check the campaign's **Agent assignment** setting. If it's **Selectable**, being assigned doesn't put an agent on the campaign — they also have to opt in. **How to fix:** Have the agent select the campaign from their own workspace, or switch assignment to **Forced** — see [Campaign settings reference](/outbound/campaigns/campaign-settings). ## Cause: the queue is skills-based, and the agent is missing a required skill **How to check:** Confirm the queue's strategy is **Skills-based**, then compare its required skills against the agent's own skill tags — the agent needs every one, not just some. **How to fix:** See [Add queue members and skills](/inbound/queue-membership-and-skills). ## Cause: no calls are actually waiting **How to check:** Check the queue's depth on the [wallboard](/supervise/wallboard) — zero waiting callers means there's nothing to route. **How to fix:** Nothing to fix — this is expected. ## Cause: the agent isn't actually registered **How to check:** See [Connect a device and check registration](/voice/devices-and-registration) — an agent can appear **Available** in the app while their softphone isn't registered. **How to fix:** Have them reload the workspace or check their [audio setup](/agent/sign-in-and-audio-setup). ## If none of this worked
