Call routing
What is Call routing?
Call routing is the process of directing an incoming phone call to the right queue, agent, department, or destination based on a set of criteria — such as the caller's number, the menu option they pressed, the time of day, or the skills required to handle their request. Instead of every call landing on a single line or ring group, a routing engine evaluates each call against configured rules and sends it to the destination most likely to resolve it, which is what keeps wait times down and first-contact resolution up as call volume grows.
More detail
Routing criteria range from simple (time-of-day schedules, round-robin assignment) to attribute-based rules that match a call to an agent by skill, language, or region, and most platforms let several rule types combine — an IVR menu choice can narrow the queue, then a skills rule picks the specific agent inside it.
Call routing is the umbrella behaviour; an ACD (automatic call distributor) is the system that executes it in a contact center, pulling the next call off a queue and assigning it to a specific agent according to the configured routing strategy.
When no agent or queue qualifies — outside business hours, or every eligible agent busy with overflow disabled — a routing plan typically falls back to call forwarding to another destination, voicemail, or a callback offer rather than dropping the call.
Frequently asked
- Is call routing the same thing as an ACD?
- Not quite. Call routing is the general concept — directing a call to a destination based on criteria. An ACD is the specific contact-center system that performs routing at scale across queues and agents, applying a configured strategy to pick which available agent gets each call.
- What criteria can a call be routed on?
- Common criteria include the caller's phone number, the IVR menu option selected, business-hours schedules, agent skills or languages, customer attributes from a CRM lookup, and current queue depth — most routing engines let several of these combine into one rule chain.
- What happens when call routing finds no available destination?
- A well-configured routing plan defines a fallback: routing to a secondary overflow queue, offering the caller a virtual callback instead of holding, forwarding to another number, or dropping to voicemail — rather than leaving the caller on hold indefinitely or disconnecting.
