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

Something you can consider since tel:5553334444;ext=123 only works for less than 4.0 and tel:5553334444,123 works for 4.0+ would be to check the user agent and put out the appropriate one.
