Telephone number harvesting is possible anyway without the tel: attribute. It's not that difficult to write a parser to extract phone numbers from plain/html text. It's much, much less of an issue than email harvesting as it is so cheap to send an email. A phone call costs money and takes time. Plus of course I've never ever heard of this being an issue to anyone. So I really wouldn't worry about it.
If you are still concerned about it, I suggest you read up on email obfuscation techniques. Very briefly these are:
Scramble the data server-side, and decode it in javascript (but what happens if js is off?)
Use an image
Hide behind a captcha (requires user intervention, is a pain)
And of course none of these are bullet proof anyway, a determined harvester can work round all of these. And don't forget human slave farms in the far east.
Not sure what you are looking for exactly, and I don't know about obfuscating phone numbers, but you could try a CAPTCHA (although that wouldn't work well for some users, and is annoying to almost all users) and/or using a phone forwarding service like Google Voice, which would allow blacklisting numbers, or pulling the plug on all phone calls if it becomes a problem.
I don't think it will become a big problem for you, as phone calls are as cheap or easy as an email message, and it isn't as easy to hop phone numbers as it is to switch email addresses, so it might be possible to keep up with blacklisting numbers.

无论如何，没有 tel: 属性，电话号码收集也是可能的。编写一个解析器从纯文本/html 文本中提取电话号码并不困难。这比电子邮件收集问题要小得多，因为发送电子邮件的成本非常低。打电话既费钱又费时间。当然，我从来没有听说过这对任何人来说都是一个问题。所以我真的不会担心。
如果您仍然对此感到担忧，我建议您阅读电子邮件混淆技术。简单来说，这些是：
当然，这些都不是无论如何，坚定的收割机可以解决所有这些问题。不要忘记远东的人类奴隶农场。
tl;dr：说实话，这不值得。

tl;dr: honestly, it's not worth it.
不确定您到底在寻找什么，而且我不知道混淆电话号码，但您可以尝试验证码（尽管这对某些用户来说效果不佳，并且对几乎所有用户来说都很烦人）和/或使用像谷歌语音这样的电话转接服务，可以将号码列入黑名单，或者在出现问题时拔掉所有电话的插头。
我认为这对您来说不会成为一个大问题，因为电话与电子邮件一样便宜或简单，而且切换电话号码并不像切换电子邮件地址那么容易，所以可能是可以跟上黑名单号码。
