Call Queues for Contact Centres

Queue strategies (PRO and AI Edition)

• Round-robin - calls cycle through agents in order.
• Longest-idle - call goes to whoever’s been free longest.
• Hunt - ring all agents simultaneously, first to pick up wins.
• Skills-based - match call to best-matching available agent.
• Priority - VIP callers jump the queue.
• Hunt by random - randomised order, useful for sales teams to keep things fair.

Callback option - the conversion lift

A 5-minute wait at peak hours leads to ~30% abandonment. Offer callback instead and abandonment drops to single digits - and the lead is preserved. Standard pattern: after 60 seconds in queue, offer “press 1 for a callback when an agent is free”. The queue keeps the position; when an agent becomes available the system dials the caller back automatically.

SLA alerts

Set thresholds (e.g. “alert if queue depth > 8” or “alert if longest wait > 2 minutes”). When breached, the queue manager gets a notification (email, SMS, Teams channel) and can rebalance - bring in overflow agents, increase priority routing, change the script.

No per-agent fees

Every other major contact-centre platform charges per agent per month, typically $40–80+. With 3CX, the agents are just extensions on the system you already licence. A 50-agent contact centre on AI Edition costs the same as a 5-agent contact centre on AI Edition - the system size is what you pay for, not the headcount.
