### FAQ

#### Do I need a user-id and password when setting the remote end of the trunk?

No. We authenticate on IP address or by registration. So, you can choose your type of connection.

#### Can I blend my caller-id (name) with my trunk and certain phone numbers?

Yes. If you set a default caller-id (name) on your trunk then all phone number caller-id (name) values will override your trunk caller-id (name). If there isn't a phone number override then your trunk caller-id (name) will prevail.

#### I don't see a place to setup a failover trunk or failover number. How do I do this?

We support failover trunking and routing. However, we currently only support this at the phone number level. If you wish to setup a failover trunk then you would build the trunk and then assign failover settings in Phone Number Management.

#### When will my new trunk become active?

Your new trunk will attempt to auto-provision within approximately 60 seconds. If it does then our routing systems will bind to it immediately.
