Hi Klaus,

I work for a company called Smile Communications based in Johannesburg,
South Africa (although legally registered in Mauritius) and we are a startup
mobile comms company focussing on providing low cost voice and messaging
services to underserved (bottom of the pyramid) customers across Africa. We
have spectrum and operator licenses in Uganda, Tanzania, Nigeria & DRC thus
far and are trying to acquire more as we go along. We launched in Uganda 18
months ago by rolling out our own Wimax network and fixed-wireless
wimax/voip phones. We are now looking at rolling out in our other licensed
countries. We built an entire voice/messaging stack integrating over 40
different open source projects using an SOA methodology.

We have now decided that with the slow uptake of Wimax voice handsets (in
fact, no uptake :( ) we will now roll out LTE in our spectrum instead. This
necessitates us to move our architecture from something slightly proprietary
(although it is all based on SIP) to obey the IMS/VoLTE specifications.

Following our previous approach, we want to build the end to end IMS/OSS/BSS
architecture in as cost effective manner as possible. We live by the motto
that our customers make a decision to either eat lunch or make a phone call
with the money they have at any given time - we want to make our calls as
affordable as possible and hence keep our Capex and Opex costs as low as
possible. We also want to have great flexibility and be able to make changes
quickly without needing to call on product vendors.

At the same time our motto is provide back to the community - hence us
publishing all the stuff we are going to do SR ;)
