If I use tel: I should write the international phone code, like that. 如果我使用tel:我应该这样写国际电话代码。
<a href="tel:+6494461709">61709</a>
So far, so good, but I can't find information on how to write a cell phone number in an "international" way, if there is one. 到目前为止，还算不错，但是如果有的话，我找不到有关如何以“国际”方式写手机号码的信息。

When dialing a number within the country you are in, you still need to dial the national trunk number before the rest of the number. 在您所在国家/地区内拨打号码时，仍然需要先拨打国家中继号码。 For example, in Australia one would dial: 例如，在澳大利亚，您会拨打：
0 - trunk prefix
2 - Area code for New South Wales
6555 - STD code for a specific telephone exchange
1234 - Telephone Exchange specific extension.
For a mobile phone this becomes 对于手机来说，这变成了
0 - trunk prefix
4 - Area code for a mobile telephone
1234 5678 - Mobile telephone number
Now, when I want to dial via the international trunk, you need to drop the trunk prefix and replace it with the international dialing prefix 现在，当我想通过国际中继拨号时，您需要删除中继前缀并将其替换为国际拨号前缀。
+ - Short hand for the country trunk number
61 - Country code for Australia
4 - Area code for a mobile telephone
1234 5678 - Mobile telephone number
This is why you often find that the first digit of a telephone number is dropped when dialling internationally, even when using international prefixing to dial within the same country. 这就是为什么您经常发现在拨打国际电话时，即使使用国际前缀在同一国家/地区内拨打电话时，电话号码的第一位数字也被丢弃的原因。
So as per the trunk prefix for Germany drop the 0 and add the +49 for Germany's international calling code (for example) giving: 因此，按照德国的中继线前缀，将0删除，然后将+49用作德国的国际电话代码 ，例如：
<a href="tel:+496170961709" class="Blondie"> Call me, call me any, anytime <b>Call me (call me) I'll arrive</b> When you're ready we can share the wine! </a> #4楼

As an additional note, you may also add markup language for pausing or waiting, I learned this from the iPhone iOS which allows numbers to be stored with extension numbers in the same line. 另外，您还可以添加标记语言以暂停或等待，这是我从iPhone iOS中学到的，它允许数字与分机号存储在同一行中。 A semi-colon establishes a wait , which will show as a next step upon calling the number. 分号建立一个wait ，它将在呼叫该号码时显示为下一步。 This helps to simplify the workflow of calling numbers with extensions in their board. 这有助于简化在其分机板中拨打电话的工作流程。 You press the button shown on the bottom left of the iPhone screen when prompted, and the iPhone will dial it automatically. 出现提示时，按iPhone屏幕左下方显示的按钮，iPhone会自动拨号。
<a href="tel:+50225079227;1">Call Now</a>
The pause is entered with a comma ",", allowing a short pause of time for each comma. 暂停用逗号“，”输入，每个逗号的暂停时间很短。 Once the time has passed, the number after the comma will be dialed automatically 时间过后，逗号后的号码将自动拨打
<a href="tel:+50225079227,1">Call Now, you will be automaticlaly transferred</a>
