Overview
The Digium Redundancy Series of products, R-Series, are versatile
devices used to facilitate physical layer switching of PSTN interfaces for
Asterisk based redundant PBX configurations. R-Series is among several
key technologies Digium is introducing to empower Asterisk integrators
to create advanced high-reliability failover solutions.
The basic application sequence shown below depicts the following:
1. While in a normal state, the R-Series unit routes the input lines from
the PSTN to Server A (Primary).
2. After a failure of Server A, the R-Series unit routes the input lines
from the PSTN to Server B (Secondary).
3. After Server A recovers, the R-Series unit continues to route the input
lines from the PSTN to Server B.
4. After a failure of Server B, the R-Series unit routes the input lines
from the PSTN to Server A.

There are a variety of applications where the R-Series units can prove
useful.

Chapter 1: Overview
What is Asterisk®?
Asterisk is the world’s leading open source telephony engine and tool kit.
Offering flexibility unheard of in the world of proprietary
communications, Asterisk empowers developers and integrators to create
advanced communication solutions...for free. Asterisk is released as open
source under the GNU General Public License (GPL), and it is available
for download free of charge. Asterisk is the most popular open source
telephony software available, with the Asterisk Community being the top
influencer in VoIP.
Asterisk as a Phone Switch (PBX)
Asterisk can be configured as the core of an IP or hybrid PBX, switching
calls, managing routes, enabling features, and connecting callers with the
outside world over IP, analog (POTS), and digital (T1/E1/J1/BRI)
connections.
Asterisk runs on a wide variety of operating systems including Linux,
Mac OS X, OpenBSD, FreeBSD, and Sun Solaris. It provides all of the
features you would expect from a PBX including many advanced features
that are often associated with high end (and high cost) proprietary PBXs.
Asterisk's architecture is designed for maximum flexibility and supports
Voice over IP in many protocols, and can interoperate with almost all
standards-based telephony equipment using relatively inexpensive
hardware.
Asterisk as a Gateway
It can also be built out as the heart of a media gateway, bridging the
legacy PSTN to the expanding world of IP telephony. Asterisk’s modular

Digium, Inc. Page 15
Chapter 1: Overview
architecture allows it to convert between a wide range of communications
protocols and media codecs.
Asterisk as a Feature/Media Server
Need an IVR? Asterisk’s got you covered. How about a conference
bridge? Yep. It’s in there. What about an automated attendant? Asterisk
does that too. How about a replacement for your aging legacy voicemail
system? Can do. Unified messaging? No problem. Need a telephony
interface for your web site? Okay.
Asterisk in the Call Center
Asterisk has been adopted by call centers around the world based on its
flexibility. Call center and contact center developers have built complete
ACD systems based on Asterisk. Asterisk has also added new life to
existing call center solutions by adding remote IP agent capabilities,
advanced skills-based routing, predictive and bulk dialing, and more.
Asterisk in the Network
Internet Telephony Service Providers (ITSPs), Competitive Local
Exchange Carriers (CLECs) and even first-tier incumbents have
discovered the power of open source communications with Asterisk.
Feature servers, hosted services clusters, voicemail systems, and pre-paid
calling solutions, all based on Asterisk have helped reduce costs and
enabled flexibility.
