This webinar provided an overview of using the snom PA1 for multicast paging with SIP-based phone systems and UC solutions like Microsoft Lync. The snom PA1 allows organizations to integrate their existing paging infrastructure with an IP phone network, avoiding costly replacement of legacy equipment. The PA1 acts as both a listening device to receive multicast pages and as a multicast relay server to broadcast pages to IP phones and PA1 devices. The presentation demonstrated how to configure the PA1 for multicast listening and broadcasting to support multi-zone paging applications in various industries.

1. Multicast Paging with the
snom PA1
Leveraging paging for a wide range of
announcements in many situations.

2. Paging
Paging is the vocal
announcement to alert people
or locate a resource.
The question is, “Where would
you not need paging?”

5. What You Will Learn from
This Webinar
This webinar will:
o Provide an overview of the new snom PA1 release
with support for multi-cast paging.
o Offer step-by-step instruction on how to provision and
deploy snom phones and the PA1 with SIP–based PBX
solutions or with unified communications solutions
like Microsoft Lync.
o Describe PA1 use cases – Deploying the snom PA1 for
paging in hotels and hospitals; how the hospitality
and healthcare industries are leveraging the
efficiencies of VoIP communication with their existing
paging systems thanks to the PA1 digital amplifier

6. Paging Applications
• Phone to overhead speaker and phone to
phone
• Paging uses:
o Announcements
o Emergencies
o Locating resources (people, equipment,
functions….)
o Schedules
o Status

7. Paging and VoIP
• Paging has been over separate networks
• Why over IP networks?
o Existing infrastructure can be leveraged
o IP multicast
o IT support
• How does paging fit with VoIP?
o Integrate with IP phone networks
o Universal or restricted IP phone network

13. Q: How do you keep or add an intercom system to
your your SIP IP PBX or UC platform?
A: snom PA1 (Public Amplifier One)

14. The Business Problem:
• Many organizations using legacy PBX systems also manage
public address/paging systems in the ceiling and/or network
of phone(s)
• When organization migrate to IP PBX or UC systems, it
requires often a change-out of the PA system infrastructure
• Converting from a legacy PA system to new IP based SIP/IP
based speaker system is costly
• Why change out something that works?

15. The Solution:
snom PA1 can bridge this SIP upgrade and
serve two roles within your paging system
• Listener: Listen to and broadcast to
speakers/amplifiers on a SIP call
 Send to one speaker via included 4 watt amplifier
 Drive an amplifier for multiple speakers in large
rooms
• Server: Multi-cast Relay to listening PA1s and snom
phones.

16. A Picture is worth a Thousand Words

17. Three Zone PA Example
Typical multicast IP addresses
224.0.0.0:port# to 239.x.x.x:port#
Classroom
Multi-cast id: 224.1.1.1
224.1.1.2
Broadcast:
Id1. Ext 100: All Below. (224.1.1.1:port#)
Id2: Ext 200: Classroom and Hallway
(224.1.1.2:port#)
Id3: Ext 300: Admin Office only (224.1.1.3:)
Hallway
Multi-cast id: 224.1.1.1
224.1.1.2
Admin Office
Multi-cast id: 224.1.1.1
224.1.1.3
