html href =“ tel：4442727,2”或href =“ tel：4442727p2”在Android上不起作用

Question

As title mentions, in my mobile web site I can call a number but I need to add a 2-3 seconds pause to the call in order to dial the extension. No matter what I tried I cannot achieve this. Both href="tel:4442727,2" nor href="tel:4442727p2" works on android (I tested on 5.1). When I use a comma it works on iOS but not on Android What am I doing wrong?

Answer 1

Try changing it to three commas - I've seen this correct the problem in the past.

href="tel:4442727,,,2"

Alternatively, replace the comma with a 'w' and Android will dial the phone number then prompt you to hit a button before dialling the extension.
