I'm not sure it's the shell that's expanding the variable:

The shell is the only thing that does expand wildcards, unless you have written something else to do it.

Code:
$ echo "some_command \* options"
some_command \* options
$ echo "some_command * options"
some_command * options


The wildcard will not be expanded if it is quoted.

meanwhile, by adding "echo $COMMAND" to my script, I get:

Code:
./test-script "some_command * options"
some_command ...list of files... options

./test-script "some_command \* options"
some_command \* options

I tried running the script from bash and ksh with the same results.

Always quote your variables (unless you have a good reason not to):
Code:
ssh "$HOST" "$COMMAND"

astgenkey

ASTGENKEY(8)						     Linux Programmer's Manual						      ASTGENKEY(8)

NAME

       astgenkey - generates keys for for Asterisk IAX2 RSA authentication

SYNOPSIS

       astgenkey [ -q ] [ -n ] [ keyname ]

DESCRIPTION

       astgenkey  This	script	generates  an RSA private and public key pair in PEM format for use by Asterisk.  The private key should be kept a
       secret, as it can be used to fake your system's identity.  Thus by default (without the option -n ) the script will  create  a  passphrase-
       encrypted copy of your secret key: without entering the passphrase you won't be able to use it.

       However	if  you want to use such a key with Asterisk, you'll have to start it interactively, because the scripts that start asterisk can't
       use that encrypted key.

       The key is identified by a name. If you don't write the name on the command-line you'll be prompted for one. The outputs of the script are:

       name.pub
	      The public key: not secret. Send this to the other side.

       name.key
	      The private key: secret.

       Those files should be copied to /var/lib/asterisk/keys

       (The private key: on your system. The public key: on other systems)

       To see the currently-installed keys from the asterisk CLI, use the command

	      show keys

OPTIONS

       -q
	      Run quietly.

       -n
	      Don't encrypt the private key.

SECURITY

       The keys are created, using the umask of the user running the command.  To create the keys in a secure manner, you should check	to  ensure
       that your umask is first set to disallow the private key from being world- readable, such as with the following commands:

       umask 0066

       astgenkey yourkey

       And then make the key accessible to Asterisk (assuming you run it as user "asterisk").

	 chown asterisk /var/lib/asterisk/keys/yourname.*

FILES

       /var/lib/asterisk/keys
