中国的电话实名对电诈虚拟号没有任何作用，因为电话网协议有“漏洞”，容许任意修改电话号码，不改现有的电话网络协议，三大运营商也没啥办法吧。

AI Overview

Telephone protocols do allow a caller to modify (or "spoof") their calling number, and this is the basis for legitimate business uses as well as fraudulent scams
.

How It Works

• VoIP (Voice over Internet Protocol): The primary way this is achieved is through VoIP services, which are widely used by call centers and businesses. In VoIP, the caller's phone system (like a PBX) can be programmed to send any desired phone number and name as the Caller ID information. Unlike traditional landlines, where the number is tied to the physical wire, VoIP is much more flexible, and the carrier historically had no built-in mechanism to verify the number belonged to the caller.
• Legitimate Uses: Businesses use this feature for practical reasons. For example, a doctor might use their personal mobile phone to call a patient but set the caller ID to display the main hospital number so that the patient calls the general office back instead of the doctor's private line.
• Illegitimate Uses (Spoofing): Scammers exploit this flexibility to deceive recipients. Common tactics include "neighbor spoofing" (displaying a number with the same area code and prefix as the person being called to make it look local) or impersonating a trusted entity like a bank or government agency.

Regulation and Countermeasures
Due to the prevalence of scam calls, regulatory bodies like the CRTC in Canada and the FCC in the US have mandated the implementation of a new caller ID authentication system called STIR/SHAKEN. This system is designed to verify that the caller is authorized to use the number being displayed, helping carriers identify and block spoofed calls.
Despite these efforts, caller ID is not a reliable form of authentication and should not be trusted implicitly. Authorities advise verifying the identity of unexpected callers through independent means (e.g., hanging up and calling the organization back on a number you know to be genuine).

北美的虚拟号也是中国搞的？

电诈指责某个运营商有点像用命案现场发现的枪指责造枪厂家。

虚拟号码就跟枪支，VPN一样，既可以用来干好事，也可以用来干坏事，如果要彻底解决，直接禁了就可以，但是那应该是管理部门干的，不是运营商干的

这个话题我特想说下自己观点，我在运营商工作了十几年，先抛开这个要求的政治背景，就说该新闻的理解

1，FCC 是什么
FCC 是 美国联邦通信委员会（Federal Communications Commission），类似中国工信部，但是他只是通信管理的一个部门，根本无权决定外国运营商是否接入美国，有投票权而已。而且FCC对中国和其他国家的类似要求，不止一次，都有各种背景提出的。

2，本次要求的核心是什么
最核心的就是，修复 反自动拨号骚扰电话数据库 (Robocall Mitigation Database, RMD) 认证问题。
RMD 认证就是：
所有想把电话流量接入美国电话网的运营商，必须向 FCC 备案并证明“我有办法防止自动拨号骚扰电话（robocall）”，否则美国运营商不得与其互联。

普通话就是，

• 美国电话网 = 小区大门
• FCC = 物业
• RMD = “允许进门的快递公司名单”
• 认证内容 =
  你是不是乱送广告、骚扰电话？
  出问题了，能不能找到你、管住你？

而这次的快递公司名单，就是三大运营商（不是具体电话号码）

3，认证内容最核心是什么
有办法防止 自动拨号骚扰电话（robocall）。
也就是，
第一类，电话不是人工逐个拨的，而是用电脑程序或自动系统批量拨打。可以在几秒内打上千个号码。不是人工说话，而是录音或合成语音播放。
第二类，假冒的骚扰或诈骗电话。

4，FCC自己能实现吗？
对于第一类，快速拨打非人工那种，技术上非常好实现，FCC，中国运营商都可以做到。
对于第二类，FCC也做不到，只是能建立某种机制，说简单就是，我有制度，我做了，有成效，只有更好没有最好。
比如黑白名单管理，举报机制，行为分析判断等

结论
1，基于此，我觉得，十来天，报备FCC，已经建立了制度，完全没有问题。长效能降低的就是第一类问题而已。
2，指责中国的诈骗电话有技术实现，只是不干。完全胡说。十几年前就有行为分析，欺骗分析，但是只要不是100%，哪家运营商敢主动停机？只能事后诸葛亮联合相关部门处理而已。
网络风暴就是流量而已，北美也没有实现FCC要求，大家还能经常收到莫名奇妙短信（这就是试探号码是否在用，定位是否可养号进一步诈骗）

这个说到点子上了，运营商是能解决的，虽然不能100%解决。中国电话是实名制的，只是三大运营商下面基层部门为商业利益偷偷发号码……

你们没弄明白问题，跟中国号码无关

Is this related to China or USA phone numbers?
This action specifically impacts USA phone numbers and calls entering the U.S. network.
U.S. Numbering Resources: These providers often use or transit traffic that utilizes the North American Numbering Plan (NANP)—the +1 country code system used by the U.S.
The Goal: The FCC is trying to prevent foreign entities from using U.S. phone numbers to "spoof" calls or flood U.S. consumers with illegal robocalls.
The Impact: If these companies are removed from the RMD, any call they attempt to send into the U.S. (even if it looks like a U.S. number) would be blocked at the "gateway" by U.S. carriers like AT&T or Verizon.

It might seem strange for a Chinese company to have U.S. phone numbers, but China Telecom Global (CTG) and its subsidiaries have historically operated as a bridge for millions of people and businesses moving between the two countries.
这些号码很多不是固定人使用的，所以实名制根本跟这个无关

2. Why is this action different?

In the past, the FCC removed companies from the RMD primarily for technical failures (e.g., failing to submit a proper mitigation plan). In these new orders:
National Security Focus: The Bureau stated that even if these companies fix their paperwork, they may still be removed because their presence in the U.S. network is "contrary to the public interest" due to potential exploitation or influence by the Chinese government.
Burden of Proof: The FCC is now forcing these companies to prove that they are not a threat to national security to stay in the database.

3. Is this related to China or USA phone numbers?
This action specifically impacts USA phone numbers and calls entering the U.S. network.
U.S. Numbering Resources: These providers often use or transit traffic that utilizes the North American Numbering Plan (NANP)—the +1 country code system used by the U.S.
The Goal: The FCC is trying to prevent foreign entities from using U.S. phone numbers to "spoof" calls or flood U.S. consumers with illegal robocalls.
The Impact: If these companies are removed from the RMD, any call they attempt to send into the U.S. (even if it looks like a U.S. number) would be blocked at the "gateway" by U.S. carriers like AT&T or Verizon.

明确说了，不是诈骗问题，即使解决了诈骗问题，也要停止：

The Bureau stated that even if these companies fix their paperwork, they may still be removed because their presence in the U.S. network is "contrary to the public interest" due to potential exploitation or influence by the Chinese government.

就是中美贸易战的一部分，反正不停折腾脱钩，又脱不干净

第一类问题，和号码无关，和实名也无关，技术就能解决。
第二类问题，和号码无关，和实名也无关，是根本无法解决，或无法根治，FCC也没办法。
