I need a way into a PA system that is accessed through a voip phone extension. Which should be as simple as calling with the correct extension I believe. How could I discover the correct extension for accessing the system and are there any other issues I could encounter. Would I need to use a voip phone on the system to call in or could it be done remotely? Thank you in advance.
