Notes:
(1) Tel-Sentry claims to be able to eliminate 99.9% of live solicitor calls by playing a standard (non-changeable) voice warning message that says “If you are a telemarketer or a solicitor of any purpose please hang up and remove our phone number from your list, otherwise please press 0”. However, in the real world 99.9% of the actual solicitors and telemarketers simply ignore this message and press 0 to reach a real person, especially politicians, charities, and scam artists.
(2) According to factory in China that manufactured both of these devices (please pay attention to the model and the HS code printed on both devices), the SENTRY has the same storage capacity as the T-Lock/Pro Call blocker. However, there is some conflicting data according to the information printed in the packaging box, it says “1000 Black / White List” capacity. Also, you will find some conflicting / incorrect information posted in Amazon & eBay by Tel-Sentry about this feature.
(3) One important detail to be aware of is that the 1,500 storage capacity available in the SENTRY device is shared among 2 lists: the Whitelist and the Blacklist. Therefore depending on the number of phones you need to store in the Whitelist, it will reduce the capacity to store numbers in the Blacklist. While the T-Lock/Pro Call blocker device has the entire 1,500 storage capability available to store Blacklist numbers.
Why is it important to have a call blocker device with a large storage capacity?
Phone scams & frauds have grown exponentially in the US and abroad in recent years. US residential consumers are getting bombarded by several forms of scams and frauds (learn more about scams). As per our current list of scam related phone numbers, there are over 600+ numbers. These are just a few of the numbers being reported by victims of scams within the last 12-18 months!
(4) Tel-Sentry claims that there is no setup require yet according to the information printed in the user guide, customers must choose a language by pressing a button to rotate through options. Without doing this this device will not work!
