Routing filters split a call flow into paths, so each call goes to the destination that fits when it arrives or where it comes from. This page covers the Time of Day, Day of Week and Caller ID Prefix filters.

Warning

The Time of Day, Day of Week and Caller ID Prefix filters are available on the Marketing and Agency plans, and during a trial.

Route by time of day

Note

To route calls based on day of week instead, see: Route by day of week.

The Time of Day filter lets you route calls to different destinations depending on when they arrive. For example, business-hours calls to your sales team and after-hours calls to voicemail or an on-call mobile.

    Go to Call handlingCall Flows and click Create, then From Scratch.

Route by caller location

The Caller ID Prefix filter reads the first digits of an incoming caller’s number (country code or area code). Then, it routes the call to the destination you assign to that prefix.

This powers Geo-routing: the ability to send callers to a local office, regional team, or franchise branch based purely on where they’re calling from.

Common use cases include:

  • Routing Chicago-area calls (1312) to a Midwest sales team.
  • Sending UK callers (44) to an international support line.
  • Blocking entire country codes from reaching your numbers at all.

How geo-routing with Caller ID Prefix works

When a call arrives, Nimbata checks the caller’s number against the prefixes you’ve configured. If there’s a match, the call follows the path you defined for that prefix. Any number that doesn’t match a configured prefix follows the default “remaining” path (All other prefixes), which you also define.

Tip

You can configure as many prefix routes as you need. Prefixes can also be used to route anonymous calls, send certain regions straight to voicemail, or hang up immediately.

Set up geo-routing

  1. Open the Call Flow Builder

    Go to Call handlingCall Flows and click Create, then From Scratch, to create a new call flow.

  2. Add the Caller ID Prefix filter

    • Click the + button on the canvas, above the Dial step.
    • Select Caller ID Prefix from the Filters menu.

    This creates two branches: a prefix branch, which keeps the Dial that was there, and All other prefixes, which has no routing action yet.

    Click Caller ID Prefix (1) under Filters.

  3. Enter the prefixes you want to isolate and define what happens to them

    • Type the prefixes you want to handle differently into the prefix field (1). Press Enter, space or a comma after each one. A prefix always starts with the country code and has digits only, up to 10, with no +: 44 for the UK, 1312 for Chicago. You can also type a US state code, such as TX, or anonymous for callers who hide their number.
    • Below that branch, set the routing action for those callers: switch its routing step to Hang up or Voicemail under Instead, or keep Dial and pick a specific destination.

    Type each prefix into the field (1).

  4. Define what happens to all other callers

    • Click the + button on the All other prefixes branch (1).
    • Select the routing action for everyone who doesn’t match a defined prefix.

  5. Add additional prefix routes as needed

    • Click the + above a Caller ID Prefix block and select Split to add another prefix branch, then repeat steps 3 and 4 for each additional region or country you want to handle differently.
    • Connect each new prefix branch to its appropriate routing action.
