Adding my Voip Provider

I have registered an account with voipstunt.com

I have added a trunk which has the following info:

host=sip.voipstunt.com
username=******
secret=*****
type=peer

When I look at my panel and the “system status” page, they all indicate that my trunk is online. They however stay green no matter what username and password that I use. When I try and call I am told that I can’t be connected at present which makes me think that my voipstunt is not registering.

Not sure where to go from here or what to do
