I see this document
But when I search in NetPros, I see a lot of examples of FXO and PLAR.
Basically, we want to use the IP phone, hit a speed dial button, the FXO/FXS goes off hook (PLAR) to a provider. I cant get the provider to tell me what the heck he has. If he is providing ring tone or not would tell me to use FXO or FXS correct?
Or does it matter since its PLAR? (I believe for outgoing only)
