Pulse Secure Duo Authentication using phone call for VPN connection if you have multiple phones registered

Many of my corporate readers have asked me to write on this topic. And, when it actually happened with me as well, I was prompted to write. So, my readers this is on your demand ;)

Sometimes, you have more than one phone numbers registered in your Duo account. And you need to authenticate for your VPN connection.

Normally, you can do following:

1. phone
2. push to Duo application on that mobile
3. VPN key copied from application, etc.

In phone case, you get a call on the phone registered. It will then ask you to press any key, in case you expect this call. If you press any number, the call gets authenticated.

But, if you have say 3 phones registered then what to do?

The solution is pretty simple!

Use - phone or phone2 or phone3 command etc.

Command: phone 

It shall call that phone. For first phone, default phone would work. For second phone, you need to use phone2 command. And so on.

Cheers ;)
