Appendix BThis appendix contains a technology survey of 3rd party products andprovides a summary of capabilities and cost ranges. There are thousands of 3rd party products and services. This survey is a sample of the3rd party vendors. Samples are across the following four categories:1. Inline – telephone line to the device and then to phoneIncoming line2. Phone/DeviceIncoming lineDevice has capabilities built-ine.g. Panasonic Dect 6.0 phone can black/white list3. ServiceCall is transferred to “sas” where it is screened. If approved, call is then sentto home phone. This service is configured via the web and requires the calltransfer capability *72 and *73Call has simultaneous ring at Nomorobo site and home. If number is on Nomorobo’s list of fraudulent calls, call is terminated at Nomorobo site. Requires the ability to have simultaneous ring. Configure at nomorobo.com.4.

3rd Party SummaryThe black circle is an indicator of whether the solution complete supports a feature. For instance, Telezapper gives a “disconnected” tone to the caller to fool computer calling systems tobelieve the phone is disconnected and removed the number from their database. This productwill still allow calls. If the robocaller doesn’t remove the number from their database, the callcould still reoccur. 20 toID 50Robo Defeaters 25 toe.g. Telezapper* 35Call Blocker with 40 toManual Touch 60Call Blocker with 60 toLarger Display 90Call Blocker with 40 toCapabilities 60Call Blocker with 50 toMost Capabilities 1203rd PartyProvidedPriceRangeSmartphones*Free – inApps – e.g. iOSFree to& Android 10Wireless Carrier 5 to 10Services**recurringText BlockCall ScreenText ScreenRejectDo NotBlacklistBlacklistWhite ListWhite ListAnonymousDisturbCall BlockText BlockCall ScreenText ScreenRejectDo NotBlacklistBlacklistWhite ListWhite ListAnonymousDisturbSophisticationCallerCall BlockLowPriceRangeHigh3rd PartyDevicedevicePage 11

In particular, the goals of this document are:– Outline valid threat scenarios for spoofed calls comingto 2G and 3G CS domains;– Analyze and evaluate ifany tools in 3GPP can beused to counteract spoofedcall detection and prevention;– Study and identify anyother suitable techniques ormechanisms for spoofed calldetection and prevention.Open to the industry, government and academia, theupcoming Voice and Telephony Anti-Abuse Workshopwill feature leading industryand government speakersaddressing robocalls, callerID spoofing, voice phishingand other issues. Hosted bythe M3AAWG VTA SIG, itwill continue the work toidentify key threats and actions to help reduce telephone services exploitation.Other Important LinksPublishedDocuments
