⚡Quick answer -
A line is one concurrent call path. Each live call—whether inbound or outbound—occupies one line. If you have 10 lines, you can handle up to 10 simultaneous calls (queuing, IVR, or talking). When all lines are busy, additional inbound calls fail as Lost Calls and outbound dials are blocked.
Use these steps if you want to:
• find your current line pool and utilisation,
• understand how lines are shared between inbound and outbound, and
• decide when to purchase more capacity.
Term | Meaning |
Line / Channel | One simultaneous call path (IVR, queue, ringing, talk). |
Shared pool | Inbound and outbound use the same lines. |
Lost Call | Inbound call rejected because no free line existed. |
Peak utilisation | Highest lines in use at any moment. |
• Admin or Billing role.
• Access to Dashboard → Analytics → Concurrent Calls and System Logs → Lost Calls.
• Plan limits—some plans cap total lines.

Connect with the relevant POC through Support and get your plan upgraded to have more channel lines.
• Transfers/conferences briefly use extra lines—leave 10 % headroom.
• Outbound dialer can starve inbound—throttle during peaks.
• Plan caps—some legacy plans lock at 8 or 12 lines; upgrade required.
• Long IVR / queue time holds lines; enable callback to release capacity.
Symptom | Likely cause | Quick fix |
Lost Calls spike at lunch | Agents break + outbound campaigns | Pause dialer; add lines |
Inbound rings, then busy tone | All lines busy | Buy more lines or re-route overflow |
Outbound fails randomly | Dialer hits max channels | Lower concurrency; add lines |
Line graph flat at max | Plan cap reached | Upgrade plan |
