Asterisk & VoIP is disruptive on one hand, helps mitigate risk on the other
We Have Some Work Left… Olle Johansson’s Challenge:
1. Encrypt Everything: We need to make the cost of listening in as high as possible, by default.
2. Integrate IPv6 everywhere3. Adaptive audio4. Federate or die

Let’s help each other! Start a dialogue.
Past decade+ of telephony History of paying too much for reliable and
available communications
Economy which is driving innovation towards efficiency and cost-savings
More distributed customers & operations

We need innovative solutions…
Is a D.R. Plan Really in Place? Is it documented? Well documented?
Is it practiced?
Is it living?
Answered “no” anywhere? Work left to do…
Trust and Verify Are you monitoring / alerting today? In
levels?
Do you even know when a “disaster” has happened? Reliability and availability, sure….
Fraud
Outage
Trust and Verify Alerting

Topology Overview
Design Questions: Before You Start Failover / reduced capacity plans?
Your systems and processes Provider support, certification & testing
Auto or manual failover?
Do eliminated risks justify increased investment?
Design Questions: Before You Start Expected life of the system
20, 10, 5 years?
Gradual or rip/replace? Digium VoIP gateways ~$1,300+ Edgewater Networks 4601 – T1 PRI,
MOS syslog ~$1,200+
Keep questioning/reviewing/adjusting.
Fact:Voice over IP & Asterisk beat traditional telephony, when considering disaster recovery.
Asterisk Advantages (D.R. & other): Deliver / fail anywhere
with quality internet access
Agnostic – device, provider Least-cost provider routes Eliminated contracts /
commitments in some scenarios
Agile – change in minutes vs. hours or days
1:n wire pair to calls
