Adding a trunk from a provisioned voip provider


I have an asterisk server running with 30 sip trunks of different voip providers, then today i signed up a new one to place on its trunks.

But it’s not working because it was made to work with provisioned configuration, like they told me to just access the voip adapter and set the provisioning server address.

They didnot give me the sip account details.

Did you heard some way to get these details or to set this account on asterisk as trunk?

Tell me if it’s possible, impossible or some way to hack it…

Thanks very much.
