Caller identity

Caller-name data for routing, display, and screening.

Caller Lookup gives applications and operators a way to enrich phone numbers with CNAM and caller-ID information before a call is answered, routed, or presented to an agent.

Why CNAM-enriched lookup, not just LERG

A LERG-only lookup tells you which carrier the number routes through. CNAM tells you the business name on the caller-ID record — which is what the agent or the application actually needs. VoiceTel blends CNAM, LERG, and portability data into a single query so you don't have to make three calls per inbound.

Use cases

  • Agent screen pop

    Display a caller name in CRM or helpdesk workflows before the conversation starts.

  • Inbound screening

    Use caller identity as one signal in spam, fraud, and escalation decisions.

  • Routing context

    Route known business callers, customers, or anonymous callers into different queues or workflows.

  • Batch hygiene

    Run lists through batch lookup before a campaign, migration, or data-cleanup project.

API example

Look up the caller-ID name for a phone number:

curl -X POST https://api.voicetel.com/v2.1/info/cnam/ \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "apikey": "YOUR_API_KEY",
    "cid": 2015551234
  }'
