Dashes (-) have no significance other than making the number more readable, so you might as well include them.

破折号 ( -) 除了使数字更具可读性之外没有任何意义，因此您不妨包含它们。

Since we never know where our website visitors are coming from, we need to make phone numbers callable from anywhere in the world. For this reason the +sign is always necessary. The +sign is automatically converted by your mobile carrier to your international dialing prefix, also known as "exit code". This code varies by region, country, and sometimes a single country can use multiple codes, depending on the carrier. Fortunately, when it is a local call, dialing it with the international format will still work.

由于我们永远不知道我们的网站访问者来自哪里，因此我们需要使电话号码可以从世界任何地方拨打。为此，+标志总是必要的。该+标志由您的移动运营商自动转换为您的国际拨号前缀，也称为“退出代码”。此代码因地区、国家/地区而异，有时一个国家/地区可以使用多个代码，具体取决于运营商。幸运的是，当是本地电话时，使用国际格式拨号仍然有效。

Using your example number, when calling from China, people would need to dial:

使用您的示例号码，从china拨打电话时，人们需要拨打：

00-1-555-555-1212

And from Russia, they would dial

从俄罗斯，他们会拨打

810-1-555-555-1212

The +sign solves this issue by allowing you to omit the international dialing prefix.

该+标志通过允许您省略国际拨号前缀来解决此问题。

After the international dialing prefix comes the country code^(pdf), followed by the geographic code (area code), finally the local phone number.

在国际拨号前缀之后是国家代码^（pdf），然后是地理代码（区号），最后是本地电话号码。

Therefore either of the last two of your examples would work, but my recommendation is to use this format for readability:

因此，您的最后两个示例中的任何一个都可以使用，但我的建议是使用这种格式以提高可读性：

<a href="tel:[phone]">[phone]</a>

Note:For numbers that contain a trunk prefixdifferent from the country code (e.g. if you write it locally with brackets around a 0), you need to omit it because the number must be in international format.

注意：对于包含与国家/地区代码不同的中继前缀的号码（例如，如果您在本地用括号括起来 a 编写0），您需要省略它，因为号码必须是国际格式。

-doesnt make matter but +sign is important when mobile user is in roaming
this is the standard format

-无关紧要，+但当移动用户漫游时，标志很重要，
这是标准格式

<a href="tel:[phone]">+49 (0)176 - 402 063 87</a>

You can read more about it in the spec, see Make Telephone Numbers "Click-to-Call".

您可以在规范中阅读有关它的更多信息，请参阅拨打电话号码“点击通话”。

I also found this format online, and used it. Seems to work with or without dashes. I have verified it works on my Mac (tries to call the number in FaceTime), and on my iPhone:

我也在网上找到了这种格式，并使用了它。似乎可以使用或不使用破折号。我已经验证它适用于我的 Mac（尝试在 FaceTime 中拨打号码）和我的 iPhone：

<!-- Cross-platform compatible (Android + iPhone) -->
<a href="tel://1-555-555-5555">[phone]</a>

I used:

我用了：

Tel: <a href="tel:[phone]">[phone]</a>

and the result is:

结果是：

Tel: [phone]

电话：[phone]

Where "Tel:" stands for pure text and only the number is coded and clickable.

其中“电话：”代表纯文本，只有数字被编码和可点击。

You can also use callto:########### replacing the email code mail with call, at least according to W3Cschool site but I haven't had an opportunity to test it out.

您还可以使用 callto:########### 用 call 替换电子邮件代码邮件，至少根据 W3Cschool 站点，但我还没有机会对其进行测试。
