Adding hosted Kazoo as a 2nd carrier (temporarily)

[avig2]

Hello,

I have customer with 3 users overseas (I believe using Yealink). I need to provision their phones to Kazoo, but before I factory reset thier phones I'd liketo make sure everything is working fine.

So instead of reseting thier phones is there a way I could set up the Provisioner to use "Account 2" only on these 3 phones to test that the extensions and outbound calling works before wiping the phone?
