First I will correct one thing I saw in this thread. Vonage does NOT own your phone number a third party does. This is what makes porting possible. For example my Vonage number is owned by XO communications.
To address the op question: (I can only address it can not answer it, only Vonage can do that.) Unlike your phone number, which is presented to the PSTN during call setup, Calling Name Delivery (CNAM) information is retrieved from a series of distributed databases where it is stored. There are only a few vendors that provide the actual information storage (Neustar, Verisign, etc.).
Since carriers must pay for each lookup they perform and their cost varies based on which vendor they are using for storing the information, some carriers have chosen to only poll that information from select vendors. In order for those vendors to provide attractive pricing, they not only offer varying degrees of cached information but will also sell information that is collected from a carrier when a new line is activated to various database marketing firms. The firms then sell that information to telemarketers.
I would assume when Vonage started they did not want to provide your information to these "databases" for privacy reasons. Or they may get some kind of deal for their look ups since they do not add to the database? It really is a mystery why Vonage does not want to provide this feature. At one time they may have allowed the OP CNAM to get out (in other words actually loaded it). I have been with Vonage since early 2004, and my name has been Vonage Holdings, Inc., My Phone #, My city and state, and unavailable. Currently it is city and state. |
