Calls between two PPs
To set up a call between two PPs, the same IP streams must be established beforehand.
RTP/RTCP streams are established directly between the RFPs managing the PPs, unless the
PPs are connected to the same RFP. In this case, no RTP packets are transmitted on the LAN by
the RFP.
The following figure illustrates this scenario:

Note: VoIP resources are required if an announcement is transmitted to the PP.
