Excuse the obvious question, but what is an OOPA and how do you talk on it?
OOPA is a way to call the Philippines.
»OOPA communications/Tipid Wireless to the Philippines
Of course, if your OOPA is connected to your LAN in such a way that recursive feedback occurs, it can be an Oopa Loopa.
OOPA is not to be confused with [Ooma].
