To be observerd: the target wireless network may be configured to have MAC address preventions so the
MAC address of WLAN interface of the Eye unit must be white-listed as a network client. Eye does not act
as an access point of the wireless network.
MOS test connections
MOS test is a license-controlled feature and not used in every environment. MOS test requires additional
ports to be used. MOS traffic is special-purpose traffic with identical fingerprint than any VoWLAN call
would have.
Sonar may serve numerous Eyes concurrently and therefore it is able to listen numerous UDP ports for
incoming VoIP calls. Ports are listened in per-need basis. One UDP port may serve one Eye at a time so
the number of concurrent MOS tests in single Sonar is dictated by the number of available ports that is
configured during Sonar deployment phase.
Eye has one open UDP port for VoIP calls as it communicates with single Sonar only at a time.
