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.
