2.3.8.1 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 analog volume control is bypassed and the volume level is

set to maximum.

Note SIP calls

, buffered SIP calls, multicast streams, buffered 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.

The maximum ringtone duration is 2 MB or about four minutes of ulaw audio.
