SkySwitch offers services for CNAM and Directory Listing that can be conveniently requested by following the steps listed further in this article. Directory Listing is a phone number feature that allows business details to be published in the National Local Directory Assistance and available via local 411. You may associate your business name and address with a specific phone number; as soon as your company details are published, potential customers can readily locate your business. Directory Listing requests for US DIDs take 2-3 business days to complete.CNAM Services are available from SkySwitch for both inbound and outbound traffic. When a call is received from a phone number, a lookup is done through the national carrier database to retrieve and display the associated CallerID.It is important to note that displaying CallerID is the responsibility of the receiving phone company. For example, if you call a SkySwitch DID, it is the responsibility of SkySwitch to display the correct record accurately. Similarly, if you call a Verizon number, it would be Verizon's responsibility to display the correct information. It is a common practice among phone companies to cache CallerID information. This means you may have differing results calling different destinations. The only way to correct a record you believe is incorrect is to open a ticket with the company receiving the call. For the reasons mentioned above, changing CNAM details for a phone number is unavailable for BYOT numbers or numbers in Port-In status. If you want to check that a user's Outbound Caller ID is set to ensure that the Outbound CNAM will be pulsed out, please view our Change Outbound Caller ID for a User article for instructions.Processing Directory ListingFor Directory Listing, Partners may request to add a Directory Listing for the number during the submission of the port during Step 3 or send an email to ports@skyswitch.com together with the completed Directory Listing Form.Processing Outbound CNAMThere are two ways an Outbound CNAM can be added or updated for a phone number. On Port Request SubmissionPartners may request to enable the CNAM for the number (both toll-free and regular DID) during the submission of the Port In Request in Step 3.After all, TNs/TFNs on a Port In request have been activated, the LNP team will process the Outbound CNAM/DL requests.
