To establish a call between two DECT phones, the same IP streams must be established as in the scenario before, except
the IP phone is not involved. If Direct Media is active, the RTP/RTCP connection is directly between that IP Base Station.
The following figure illustrates this scenario:
A call from one DECT phone to another that resides on the same IP Base Station will loop back within the IP Base Station,
if no IP Office is involved. So the call will not pass through to the local area network (LAN). Although the voice packets
will not impact LAN traffic, signal packets will.
