What’s the Difference Between Inbound CNAM and Outbound CNAM?

Remember back in the day--as in the 80s--when a telephone conversation would begin like this:

Person being called: "Hello? Who is this?"
Caller: "This is Becky."
Person being called: "Oh good. I wondered who was calling me."

Or if you were a teenager making a crank call:

Person being called:  "Hello?"
Caller: "Is your refrigerator running?"
Person being called: "Yes it is."
Caller: "Well you better go catch it!" [laughs and hangs up the phone]

Back then, we couldn't see any information letting us know which number we had dialed and we had no earthly idea who was calling us. It was all a mystery. (And crank calls were all the rage.) Thank goodness those days are behind us and thank goodness for CNAM. But what's the difference between the information we see vs. what the caller sees? We'll tell you...

CNAM, also commonly known as Caller ID, provides information to the person calling and receiving the call. As you may have guessed, CNAM is simply an acronym for Caller ID Name. There are two types of CNAM: Inbound CNAM and Outbound CNAM.

outbound “Caller ID” information when making an outbound call. On the other hand, Outbound provides a number with the ability to display the calling numbers “Caller ID” when receiving a call.



It's pretty simple--again, the main difference between Inbound CNAM and Outbound CNAM that you need to know is that one displays the information when making a call (outbound), and the other displays the information when receiving a call (inbound). Overall, CNAM provides valuable information that both the caller and the receiver need. Take a look at our video to learn more!

We've been telling you about add-ons that you should include with your DIDs and the CNAM feature is high up there in importance! If you think you may be missing out on the add-ons you need to make your DIDs the best they can be, take a look at this recent post of ours to check and compare.
