In your config:

line telnet 0 4

  login

  password password

  no shutdown

You'll want to fix that. Anyone in the world can access the device with the password "password". I would remove the password and shutdown the telnet access, use ssh only.

Also in the config:

no service password-encryption

I recommend enabling password encryption to prevent reading passwords from the configuration.  Issue the command "service password-encryption".

You'll also want to change all passwords on the device including SIP authentication and anything else on your network that uses the same passwords.

Also in the config:

username "admin" password “xxxxxx$"

username "enable" password “xxxxxxxx$"

Did you put the "admin" user there or was it from the default? If it's from the default, it has the password "password". Remove the admin user if you aren't using it.

Keep in mind that the web GUI interface allows changes and full access without enable. (Note to Adtran, please consider changing this to require enable password.)

Create an ACL called "admin-access" containing only the local networks you use to manage the device. Apply this ACL to line ssh, line telnet (if you use it, not recommended) and also http server and http secure-server.

http ip access-class admin-access in

http ip secure-access-class admin-access in

line telnet 0 4

ip access-class admin-access in

line ssh 0 4

ip access-class admin-access in

Create another ACL called "sip-access" containing the just subnets of your SIP provider and internal SIP users and apply that to the SIP process with:

sip access-class ip "sip-access" in
