CallerIDBlock allows you to selectively decide for which phone numbers CallerID (your phone number) is sent and for which it is supressed. This little utility is especially useful, since the standard phone CallerID feature is limited to only 3 rather restrictive options: No CallerID, CallerID for contacts only, and CallerID for all. Lets face it, in the real world you need to have
the flexibility to decide to send your CallerID for every phone number individually. For many
Telephone Service Providers (TSPs) even the restricted CallerID option will not work!

CallerIDBlock allows you to add phone numbers manually, by importing your contacts automatically, or whenever you dial a new number. Imported contact numbers do not block CallerID (by default), whereas newly dialed numbers automatically block CallerID.

Includes storage card support.

A Multi-Lingual User Interface to over 140 languages is available.
Support exists for Windows Mobile 5.0 6.0 for the PocketPC and SmartPhone platforms.
