Caller ID
From VoIP.ms Wiki
If you are placing outgoing calls, most likely you will need to pass a Caller ID. There are two types of caller ID and its important to always point the difference, these are Caller ID Name and Caller ID Number.
Please note that the caller ID is only guaranteed while using premium route, and only for US48 and Canada calls, even though you may find your caller ID working on Value route at some point.
Caller ID number
This is the most common Caller ID you will be passing. The caller ID number is just one more setting from your voip.ms account, if you are using devices like Telephone Adapters, IP phones or softphones, you require to set this from the customer portal.
To set the Caller ID number for your Main account, you need to enter the "Account Settings" from the "Main Menu" menu tab, and then head for the General Tab.
If you need to set the Caller ID number for your subaccount, you can set this at the moment of creating it, or later simply by going to the Edit page of the subaccount. It will work the same way.
It is strongly suggested to set a 10 digits valid Caller ID number, to ensure proper termination.
Caller ID name
The caller ID name is an additional information you can pass along with your Caller ID number. This will also be received on the callee's end and it could be your name or you Business.
For example: "John Smith"<9145551234>
The sample above is a Caller ID, that includes both Caller ID name and Caller ID number, commonly abbreviated as CID and CNAM among other variations.
Is not possible to set any Caller ID name from the voip.ms portal.
If you will be making calls on Canada, you can simply pass the Caller ID name from any device or system you use. You will need to check for a field on the interface from the device to enter this setting, and in case you are using a more advanced system, get assistance to set this up.
The Caller ID name on US however works different, this is controlled by a national CNAM database, with records of numbers and names matching each number. When you make a call to a US number, you will send a caller ID number, and the system will check on the CNAM database for a name matching the same Caller ID number you passed, in order to display both name and number to final phone.
CNAM is only available for US DIDs. In order to update your Caller ID on the CNAM database for your US calls, there is a process to follow which has a cost of $10 USD (one time only). Please contact voip.ms support to get further details on what information you need to submit and to confirm if your local US DID is available for CNAM update.
CNAM update is only available for Local US DIDs.
