Elastic SIP Trunking now supports Caller ID Name (CNAM) Lookup

Elastic SIP Trunking now supports Caller ID Name Lookup

  • Make informed decisions on which calls to answer by surfacing Caller ID data with CNAM Lookup.
  • Caller ID Data added to Twilio Lookup to allow you query the CNAM database on demand via REST API.
  • Retrieve CNAM data on an in-progress call and use it to query your system of record to surface relevant caller information.

Missing calls costs businesses money. Answering unwanted calls from telemarketers, robocallers, and phone spoofers cost employees time.

That’s why we’re excited to announce CNAM Lookup for Elastic SIP Trunking. Now every time the phone rings, you know who’s on the other end of the line and whether you should answer or let the call go to voicemail.

CNAM is an acronym which stands for Caller ID Name.  With CNAM Lookup, the calling party’s name is automatically displayed alongside the phone number, to help users easily identify a caller.

Enabling CNAM Lookup is as simple as navigating to the Elastic SIP Trunking Twilio Console page where you can select a SIP Trunk or create a new one, and enable the feature on the Origination page.


Enable CNAM

Once enabled, all inbound calls to this SIP Trunk from the United States and Canada will automatically perform a CNAM Lookup and display Caller ID data on your phone. Enabling CNAM Lookup costs $0.01 per inbound call.

You can also use the existing Calls REST API to retrieve the CNAM data:

$ curl -XPOST '' \
  "date_created": "Thu, 26 Oct 2017 05:48:11 +0000",
  "to": "sip:+16144260135@",
  "from": "+1408XXXXXXX",
  "direction": "trunking-originating",
  "caller_name": "Alexander Bell",

This allows you to retrieve CNAM data on an in-progress call and surface it via screen pop or retrieve customer information from your system of record based on the person who is calling.
