Outbound Caller ID Name in North America Affecting Outbound Call Connection Rates

Announcement

We have received guidance from several carriers while addressing support tickets that they are seeing many outbound calls being automatically scored as low reputation calls on many networks which results in:

  • Calls being sent directly to voicemail never actually ringing the line
  • Calls being rejected outright
  • Short Ring then silence
  • Spam Likely / Spam Designation

It is very important to take a simple step by logging into your carrier portal and setting a Caller ID Name (CNAM) value. As a reminder, this is a 15 character alphanumeric value that get's sent across with the actual phone number when you make an outbound call.

This should be set for EVERY active number.

Here is some short cuts for how to update this on the following carriers:
