Problems using extensions in tel: hyperlinks on Android 4

Question

We have a mobile web site with some phone number links, like this:

href=\"tel:12345678,123\"

This works fine on most devices, but it appears it doesn\'t work

Answer 1

According to the documentation, the tel: scheme supports RFC 3966. Reading these RFCs is a bit like reading cuneiform on clay tablets, but from what I can tell, your syntax is not part of that standard. It looks like you would want tel:12345678;ext=123.
