Configuring Advanced Features
This chapter provides information for making configuration changes for the following advanced
features:
 Multicast Paging
 Action URI
 Quality of Experience
Multicast Paging
Multicast paging allows Skype for Business phones to send/receive Real-time Transport Protocol
(RTP) streams to/from the pre-configured multicast address(es) without involving SIP signaling.
Up to 10 listening multicast addresses can be specified on the Skype for Business phone.
Sending RTP Stream
Users can send an RTP stream without involving SIP signaling by pressing a Paging soft key. A
multicast address (IP: Port) should be assigned to the multicast paging key, which is defined to
transmit RTP stream to a group of designated Skype for Business phones. When the Skype for
Business phone sends the RTP stream to a pre-configured multicast address, each Skype for
Business phone preconfigured to listen to the multicast address can receive the RTP stream.
When the originator stops sending the RTP stream, the subscribers stop receiving it.
Procedure
Configuration changes can be performed using the configuration files or locally.

Skype for Business phone to send the
