Notes/Comments
The information that you collect in Table C-3 is helpful in sizing the PSTN trunks.NoteOn-Net refers to calls that originate from and terminate on an IP endpoint. An On-Net call never requires a connection to a PSTN and uses only IP for the entire duration. Off-Net refers to a call that requires the connection to a PSTN network to complete the call.
