What is Caller ID?
There are two types of Caller ID: Caller ID Number (CID) and Caller ID name (CNAM).
CID is a service that displays your phone number to the phone of the individual you are calling (on an outgoing call).
CNAM is a service that displays the name associated with your phone number to the phone of the individual you are calling (on an outgoing call).
In the US, CNAM is controlled by a national CNAM database that serves as a log of all US names and phone numbers.
How can I set up Caller ID with Telnyx?
Inbound Caller ID Number
By default, Telnyx will provide the CLI (Calling Line Identification) number for all calls being received on a Telnyx number. Once a number is provisioned on our service, we will automatically include the caller ID number when sending you your inbound calls.
Inbound Caller ID Name
Inbound Caller ID Name will allow you to have the name of the individual calling appear on your phone when receiving calls. You can activate this feature instantly via the Mission Control portal.
To set up inbound Caller ID, log-in to your Mission Control account, click on the “Numbers” tab then “My Numbers” and select advanced options for the number you would like to modify. You can then toggle on/off the “Enable Caller ID Name” option at the bottom of the modal.
(Please see example below)
(Standard pricing for inbound caller ID name is $0.40/mo for each number)
Outbound Caller ID Number
When placing an outbound call via Mission Control, we will pass the caller ID number that you use with the call. That is, whatever CLI (calling line identification) you are sending with the call will be shown to the party receiving the call. If you do not provide a CLI, your call will go through with "unknown" displayed to the receiving party.
Note: Telnyx Mission Control provides you with the ability to setup Caller ID Override at the connection level. This will enable you to set a default outbound caller ID number for all calls for a particular connection. This would ensure that even if you do not provide a CLI when placing an outbound call, we will make sure to set the CLI to the Caller ID Override number you provide.
To set up outbound Caller ID Override you can do the following:
- Login to your Mission Control account
- Go to the Connections page
- Select "Outbound options" (next to the "Delete Connection" icon) for the connection which you'd like to set caller ID override
- Input the number you'd like displayed as your CLI in the "Caller ID Override" field.
- Select "Always" , "Normal Only" , or "Emergency Only"
- Then select the Localization Country - this allows the caller to use the international exit code of the chosen country, and also restricts national dialing solely to that country
- You may opt in for "Channel Limit" - this limits the total number of outbound calls made from this connection
- You may opt in for "Expert Settings" - ex: Ringback
- Click update
(Please see example below)
Outbound Caller ID Name
Outbound Caller ID Name is what enables you to have your Caller ID Name displayed to the receiving party that you are calling. This is done by registering a Caller ID Name for a number. To set up outbound Caller ID Name (register CNAM), simply edit the settings of the number, click the box to "Enable CNAM Listing", and type in your 15-character Caller ID Name.
(Outbound caller ID name listing is free)
CNAM for USA & Canada
The way in which caller ID name (CNAM) works is different in the U.S. as it is in Canada.
In the U.S., there are several CNAM databases that have a record of every US number and the CNAM associated with the number. When a CNAM listing is enabled on a U.S. number, the CNAM details are inserted into the relevant database.
When a call is placed between two U.S. numbers, the carrier who receives the call will check one of the databases to get the CNAM associated with the number. The carrier will pass the call along with the CNAM to the called party.
In Canada, there is no national CNAM database. Instead, the CNAM information is passed in the appropriate SIP headers. The SIP headers are:
- When enabling CNAM Listing on Telnyx owned numbers, this can take up to 48 hours to propagate and process to the industry databases.
- CNAM is not currently supported on our toll free numbers.
- When enabling CNAM Listing on numbers belonging to our underlying carriers, it can take 3-5 working days to process to the industry databases.
- Please remember, that it's up to the receiving carrier of your outbound calls to display CNAM on their subscribers phones. If the subscribers have not enabled this service with their carriers, then your CNAM may not display on their devices. By default, the destination carriers may display the rate center, locality of the callers number instead, where no CNAM value is found.
- Please also note, that the industry wide CNAM service is not generally used by Wireless Carriers. So if you dial a wireless/mobile device, your CNAM may not display on their device. The only way around this is if the subscriber includes the name as a contact in their phone-book.
You can use the number lookup tool from your account to verify when the CNAM Listing has been updated on your number.
