Sonictel PBX changing CNAM attached to DID in CNAM storage

Modified on Mon, May 6, 2019 at 4:07 PM

Fill out the attached Skyswitch "Directory Listing Order Form"

There is a one-time $7 charge associated with Directory Listing.



In order to enable CNAM Storage for a SkySwitch DID, you must submit 

the form here to the SkySwitch Control Tower 

(we are currently in the process of automating this feature).


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 accurately display the correct record. 

Similarly, if you call a Verizon number, it is Verizon's responsibility to 

display the correct information. It is 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.


Step-by-step guide to Change Outbound Caller ID Name


Outbound Caller ID Name a.k.a CNam Storage operates quite differently than its 

more simplistic sister Caller ID Number. The party responsible for delivering 

Caller ID Name is the telephone company that delivers the call to the end user. 

If CNam Storage has been provisioned for a DID then the telephone company delivering 

the call from that DID is requested in the call setup to provide the Caller ID Name. 

There are 8 CNam Storage Databases that maintain the correlation between a Caller ID 

Number and the corresponding Caller ID Name. During the setup of a call to an end 

user from a DID that has CNam Storage provisioned the telephone company delivering 

the call will lookup the Caller ID Name from one of the CNam Storage Databases and 

deliver that name to the end user. One key note is that it could take 30 days or 

more once CNam Storage is requested in order for the databases to updated with the 

requested Caller ID Name. During this time, a cached Caller ID Name or even an 

"Unknown" or "Null" could be delivered.


1.) In order to have CNam Storage Provisioned on a DID please follow the 

    instructions here.

2.) Once CNam Storage has been requested you will want to annotate that in 

    the SkySwitch Dashboard

3.) Navigate to the user's Profile Tab on the user of the DID on which you 

    desire Outbound Caller ID Name to be delivered

4.) Click inside the Caller ID Name Field and change the Caller ID Name to 

    the name that was requested to be provisioned. As stated in the note above 

    Caller ID Name is delivered via a database system by the telephone company 

    that delivers a call. So adding the Caller ID Name here on the User is not 

    changing or affecting the Outbound Caller ID Name. 

    IT IS ONLY SERVING AS AN ANNOTATION.
