4. AMD Explained AMD: Answer Machine Detection
Determines automatically if a call is answered by a live person, an answering machine, a FAX machine, etc.
Sometimes called:
CPD: Call Progress Detection
CPA: Call Progress Analysis
AMD is important for call center productivity! It screens out calls that do not need a live agent
To maximize productivity and customer satisfaction, AMD needs to be accurate and fast

5. AMD Is Performed With Algorithms (Maths)
Typical AMD algorithms use Heuristics
Heuristics means breaking complex problems into simple rules to facilitate finding a solution
For CPD, heuristics could be:
Look for short energy burst on the line = Human
Look for Longer energy burst after connect = Voice Mail
So far so good for Residential Lines, but what about calls to mobile phones?
Calls with background noise will look like Longer Energy burst
Mobiles with Music Ringback tone (aka CRBT)
Heuristics systematically label these cases as Voice Mail
Heuristic are very difficult to tune and optimize, too many knobs!
Campaigns are no longer Residential only – PSTN going away!

6. Campaigns need to blend landline & mobile calls
Approx 25% with
Wireless only!

7. Lyra AMD Algorithm: Unique Approach
We humans are very good at AMD – never fail
Sangoma wanted to mimic how the human brain does answer machine detection
In software lingo this is called Neural Networks
Lyra implements a Neural Network Optimized to perform AMD to deliver:
Very High out-of-the box accuracy
Fast Detection
Trained to recognize multiple types of calls
Mobiles, Residential, Music Ring Back Tone, etc.
Very simple tuning (if at all)

8. IBM Watson: Neural Networks playing Jeopardy!

12. 3 Phase Recognition – Divide and Conquer
Pre-connect “brain”
Specializes in detection of worldwide ringing tones, SIT tones, etc.
Post-connect “brain”
Specializes in detection of live, answering machines, fax, etc.
End-of-Message “brain”
Specializes in detection of the end of a greeting
Useful feature for outbound notification market
These combine to classify outbound calls

13. Licensing Requirements
Licenses are allocated per active AMD sessions, i.e. from the INVITE sent to the Callee until a AMD result is sent back to the dialer.
After that, the AMD license is freed, but Lyra remains in the call path until the customer/agent conversation is over.
License key files put an upper limit on simultaneous AMD sessions.
No limit on concurrent customer/agent conversations

14. Benchmarking and Accuracy
Lyra uses detection algorithm that is internally developed
To train and measure accuracy:
We have 5000 call samples
Wireline, wireless, business, MRBT, etc.
4500 are used to train the models
500 are used to test the model
Comparison to other DSP technologies out of the box (no tuning)
Very tough call set

22. Asterisk Version Support
Asterisk SIP stack needs to be patched in order to work with Lyra AMD
Generates Asterisk manager event
Patch files are provided for each Asterisk Version:
Asterisk 10
Asterisk 1.8
Asterisk 1.6
Asterisk 1.4
The Asterisk SIP stack does not change very often, thus the above patch should work for all Asterisk subversions.

23. Patching Asterisk Download Asterisk Untar Asterisk intsallation
Download Sangoma Lyra Asterisk Patch
Download appropriate patch based on Asterisk major version number.
Apply the patch
Build and Install Asterisk as per standard Asterisk build

24. Minimum Server Requirements
Dual-Core CPU (for less than 50 calls)
Quad-Core CPU (up to 200 calls)
1 GB RAM (2 GB recommended)
60 GB of available disk space
Connection to IP network

27. Many of your have heard us refer to this product over the years as:
AMD for the Masses!
AMD is not new to Sangoma; the name is new but we are veterans of this software solution
Many of your have heard us refer to this product over the years as:
“CPA” or Call Progress Analysis
“CPD” or Call Progress Detection
We know this space and we know it VERY well.
We are known as the “savers” by Genesys and Oracle when their call center customers need > then mediocrity of %

28. AMD for the Masses!
So lets be clear about this please: we are providing significantly more than AMD, we are using the term AMD because the world ID’s with AMD.
Our competitors perform AMD in hardware DSP which as Simon noted earlier is not trainable.
A few software vendors have implemented “tone detection” to guess for answering machine or live person.
