Polycom Multicast Paging Tab
10. SIP Page / Call Priority vs Multicast
Incoming and outgoing non-emergency SIP call audio streams can be programmed to have priority over any of the 10
standard multicast paging groups. Use the "SIP In Above" and "SIP Out Above" drop down menus to select which
multicast groups you want SIP calls to have priority over. "SIP In Above" is to set the priority of incoming SIP pages
and "SIP Out Above" is to set the priority of outgoing non-emergency SIP calls. Regardless of the priorities selected,
outgoing SIP emergency calls have the highest priority and will interrupt any multicast source.
Factory Setting for both: 0 (SIP is highest priority)
When Polycom is selected as the Multicast Page Type, the "SIP In Above" and "SIP Out Above" priorities can be set to
"Poly" or "None". See the following tables for the order of priorities with each setting. As shown, outgoing SIP
emergency calls have the highest priority and Polycom Group 25 multicast has the second highest priority. The priority
options allow you to determine the priorities for Polycom Groups 1 through 24 multicast signals, SIP paging and non-
emergency outbound SIP calls. Factory Setting for both: Poly
