Prosody S summary• Host media processing (HMP) software• Runs on host CPU of standard IT servers• Voice (VoIP) and fax communications applications• Enterprise and service providers• Scales from 1 to thousands of channels

Why choose Prosody S?1. Very comprehensive media processing

capabilities

• Wide range of Codecs supported – including HD Voice

• Extensive fax support T.30/T.38• Deployment proven SIP stack

Why choose Prosody S?2. Flexible deployment models

• Bare metal servers, virtual machines, hosted servers or cloud servers

• A valid proposition to build up “ hosted “ ( Private Cloud ) based SW solutions

• Linux & Windows, 32 & 64 bit• Distributed architecture• Flexible licensing – pay for what you need, per

channel

Why choose Prosody S?3. Scalability

• Scales from 10s to thousands of channels• Install only the channel quantity needed; support

for licence moves and changes to meet your capacity needs

Why choose Prosody S?4. Cost efficient

• Simple pricing, no hidden costs for extra functionality

• Pay only for what you use (per channel)• Supports startup deployments with low initial costs• Capex or Opex purchase models (buy or rent)

Why choose Prosody S?5. Robust, proven technology

Features explained – distributed API architecture

• Application software operates on centralised server• Multiple Prosody S equipped servers supported, can

be scaled to meet implementation needs– No impact to local compute resources on each Prosody S

server• Flexible scaling of site capacity

– Operational cost control– Quick response to expansion needs

• Operational integrity– 3 levels of redundancy (plus DRSS)– Failover for application control

Call centre application with distributed API

Software, distributed amongst several servers, can act as one solution

Features explained – common API with Prosody X

• Developers have only one API set to learn• Projects can be ported easily to Prosody X or

Prosody S as required– If suitably programmed (no switch API)– Professional Services available for consultancy advice

• Quicker feature development times for Aculab – faster time to market for our customers

Features explained – fax

• Both G.711 fax pass through and T.38 fax modes are supported• T.38 fax (FoIP) is intended to replace the sometimes un-reliable fax

over VoIP approach (G.711 pass through) and enable full migration to an all-IP network for all business telecom needs

Features explained – wideband (HD Voice) support

• HD Voice codecs– 20Hz to 7kHz audio bandwidth for clearer speech applications– G.722; G.722.1*; G.722.2 (AMR-WB) all available– Skype SILK– Others under consideration – EVRC-NW, Speex wideband,

Broadcom BV32, Opus• Applications

– Wideband conferencing server– Wideband enabled call centre server– Transcoding server– Gaming platforms– etc

* G.722.1 is offered as a beta version awaiting full testing

Features explained – dual redundant SIP service (DRSS)

• Ability to duplicate the SIP stacks for resilience• Bringing PSTN centric ‘five 9s’ availability

concepts to the SIP world– Fundamental requirement for telcos; becoming more important

now also for enterprises

• Recovery from failure conditions taken for granted in the PSTN, but equally valid for SIP networks

• Reactions from customers and analysts very positive – we have something unique

• Whitepaper available via website

How to purchase

• Licence purchases will be credited to a customers licensing account accessible 24x7

• Single channels or blocks of credits can be purchased in advance, used as needed

• Licence keys created by the customer as required using a web interface to our licensing database

• Rental option now available, contact us for details

• Prosody S software is licensed, granular increments– Part code ACS9200

– Prosody S single channel licence
