2.4.9.1 Assigning Priority
When playing multicast streams, audio on different streams will preempt each other according to
their priority in the list. An audio stream with a higher priority will interrupt a stream with a lower
priority.
If both SIP and Multicast is enabled, SIP audio streams are considered priority 4.5. SIP audio will
interr
upt multicast streams with priority 0 through 4 and will be interrupted by multicast streams with
priority 5 through 9.
During priority 9 m
ulticast streams the volume level is set to maximum.
Note SIP calls
, multicast streams, ring tones, ringback tones, and nightring tones are all
prioritized.
Ringtones and
Nightringtones
Ringtones all play at the same priority level. This means that it is possible to have a nightring tone
and a normal ringtone playing at the same time.
