RING CENTRAL CONFIGURATION GUIDE: SIP PAGING ADAPTER (SPA)
Doc. 931050B Page 7
For ease of installation, the SPA offers a flexible analog interface to connect to a wide variety of
analog amplifiers and zone controllers.
The Page Port output supports a standard 600 Ohms output with DTMF pass-through capability
for analog amplifiers and zone controllers requiring TEL input connections from a legacy phone
system. The SPA's RCA Line Level output allows for connections to analog amplifiers and
mixers which may not offer a Page Port or TEL input for paging. Both analog outputs can utilize
the dry relay contacts for contact closure (also known as "dry relay contact switching") to initiate
a page where required.
Our VoIP Technical Support team maintains a matrix of compatible analog amplifiers on our
website that you may use to verify compatibility and view/download sample wiring diagrams for
connections from a SIP Paging Adapter. The CyberData "Connecting to Compatible Analog
Amplifiers" matrix is available on our website here:

You are more than welcome to Contact CyberData VoIP Technical Support for assistance with
verifying connections from a SIP Paging Adapter to a specific analog amplifier or zone
controller before purchasing your device.
Need to tie in your background music? Incorporating background music from an analog RCA
Line Level source can be realized using the RCA Level Input on the SPA with options to loop
background music to the analog Page Port or RCA Line Level outputs.
When a page is made from the phone system, a multicast page is received, or a call to the
Nightringer is detected, the SPA will mute the RCA Level Input to play the page or Nightringer
tone. Background music from the RCA Level Input will resume when the page or Nightringer
call has ended.
SIP Audio Sourcing
In a RingCentral installation, the SPA can be provisioned as a free Paging Device or existing IP
phone to accept SIP calls for auto-answer paging and playing stored pages.
Figure 3-1 shows the SPA installed with a music source providing background music to the RCA
Line Level input, and the Page Port or RCA Line Level output connected to an analog amplifier
with attached speakers.
A registered RingCentral phone can make a call to a Paging Group with SPA membership. Or,
when configured as an existing IP phone to provide the abilities to play stored pages and passing
DTMF digits through the analog outputs to a connected analog amplifier or zone controller, a
registered RingCentral phone can make a direct call to the SPA's extension.
