help with sip provider configuration

[Arative]

We're in the process of switching to a sip provider. Its our local cable company, Charter. I have an adtran 3430 on site. The username is a BTN and there is no password. I set the carrier up in vicidial, basically just following the sipexample carrier. The ip of the adtran device is an internal ip. What I am seeing in the asterisk CLI is registration timed out and in sip shows peers it says it is unreachable. I've disabled the firewall on vicidial server. I'm not sure exactly where to go from here. Being unreachable would seem to indicate a firewall issues I would think.
Here is what my carrier looks like
register =>(BTN):@10.10.10.24

[BTN]
disallow=all
allow=ulaw
type=friend
username=BTN
secret=
qualify=yes
host=10.0.10.24
dtmfmode=rfc2833
context=default


ViciBox 4.01 | | 2.12b0.5
BUILD: 160106-1733 | 1.4.44-vici | Single Server | Digium TE407PF | No Extra Software After Installation

This doesn't sound right at all. If you're ISP is providing the SIP trunk then they should have given you an public IP (or potentially a set of them) to route SIP traffic to. They should also provide authentication information. Simply peering with your router makes no sense and the BTN username sounds like it's used for accessing the web interface of said router. You should contact Charter and ask them for an example Asterisk configuration.
