2.4.9.1 Assigning Priority
The device will prioritize simultaneous audio streams according to their priority in the list.
If both SIP and Multicast is enabled, SIP audio streams are considered priority 4.5. SIP audio will
interrupt multicast streams with pr
iority 0 through 4 and will be interrupted by multicast streams with
priority 5 through 9.
During priority 9 multicast streams, the v
olume is set to maximum.
Note SIP calls, multicas
t 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.
