Connections overview
Silent intrusion is not possible in all cases and not absolutely silent. For IP-IP, IP-SIP
and SIP-SIP connections, the media is switched directly and not via the system. In
these cases the connection must first be fetched into the system for the intrusion,
causing a faint crackling. Prerequisites for this procedure are sufficient VoIP licenses
and DSP resources.
