[Freeswitch-users] Authorize only certain user agents

Why would you want to? Almost any device can change the user agent it sends,
either bypassing a blacklist or hitting a whitelist when it shouldn't.

If you really want to, then it would be possible from the dialplan by
creating an extension that matches against the sip_user_agent variable and
hangs the call up before processing the rest of the dialplan.
