Problems using extensions in tel: hyperlinks on Android 4

Question

We have a mobile website with some phone numbers, for example:

href = "tel: [phone]"

This works great on most devices, but it doesn't seem to work on many / all Android 4 devices. The extension just doesn't appear in the dialer when you click a link.

Has anyone found a solution?

Answer 1

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

Answer 2

I just tested both methods with Android 2.1.

tel:[phone];ext=123 finishes dialing 358123 instead of 123, because instead it converts ext to a number.

The correct way is to use a comma.

tel:[phone],123

Tried this with our extension here, and it immediately connected me. First he dials a number, then stops, and then he hits extension 123.

Answer 3

Something you can consider, since tel:[phone];ext=123 works only on 4.0, and tel:[phone],123 works for 4.0+, it will check the user agent and pull out the appropriate one.
