VoIP without DSPs: challenges and opportunities
Agenda
An epiphany moment How’d ya do VoIP without DSPs? Some of the benefits The issues and challenges Where can you use it? A mini case study Questions Summary
My job for the next 20 minutes…
Keep you awake and engaged Provide an educational and fun experience Maintain non-commercialism Pass on some thought provoking tips centred
around the challenges and opportunities arising from VoIP without DSPs
There’s nothing like a good idea
Sometime, somewhere…
Someone had a thought along the lines of, “In an all-IP environment I don’t need a T1, so is there still a need for a DSP board?”
At this epiphany moment, he thought unto himself, “There is another way!”
Or as Nostradamus put it…
In the bright millennium in the house of greatest power
With a blinding flash that is not obscure
He will realise no need for T1s And can resources run on any
PC tower
What do we mean; VoIP without DSPs?
DSPs run firmware that performs media processing
Functions are essential for telephony systems Software-based media processing resource
functions are an alternative Software that runs on a host PC’s CPU Alongside the application Instead of firmware running on dedicated DSP
resource boards
Benefits of this approach
Terrific idea for trial or development systems Speeds time to market Cost-effective for small-scale VoIP e.g., SMEs Reduces total cost of ownership Wide choice of platforms ‘No-brainer’ network connectivity Can be offered as a package with SIP or
H.323
Issues and challenges
Functionality Channel count Small-scale systems The nature of the application Telco-grade
Where can you use DSP-less VoIP?
Small-scale IVR, voicemail IP PBX for SMEs High channel broadcast/announcements Try it out on telco-grade servers
or Blades
Mini case study
Here’s an example of VoIP without DSPs Cisco CallManager VoIP telephone system
replaced old TDM system Educational complex with its own hotel 4 separate campuses; >500 extensions Voicemail features didn’t meet customer’s
needs
Mini case study
DSP-less VoIP for enhanced voicemail Standard H.323 interface Unlimited amount of voicemail boxes and
messages Several ’add-on’ features compared to
’standard’ voicemails e.g., mobile phone voicemail box, automated attendant, information boxes, email forwarding (WAV file), browser-based user interface, IVR, etc.
The opportunities realised
No extra hardware costs for interface or resources Easy integration process Hybrid solutions possible
Various PBXs and VoIP solutions served by same voicemail/ IVR
Implementation costs are low Easy to implement, tailor, upgrade and update Delivery costs are modest

In summary
Speeds time to market Cost-effective for small-scale VoIP e.g., SMEs Reduces total cost of ownership No extra hardware costs for interface or
resources Easy to implement, tailor, upgrade and update Wide choice of platforms Blade Server is an option
Or, as Nostradamus might’ve said…
In the halcyon days of adventurous voice over IP
Great systems will be constructed
IVR and VM1 will demand resources
And they shall be found without a DSP
