connections. Each connection consists of two parts:
 Session related connections (SIP/SDP)
Audio stream related connections (RTP/R2S)

The figure below shows that a VoIP connection to the radio always consists
of both a SIP/SDP and an RTP/R2S connection. VoIP connections need to
be established for each module. Therefore, a transceiver in VoIP operation
mode will always have at least one connection to the RX and one
connection to the TX module. Note that each module can have a maximum
of two concurrent SIP/RTP sessions.
