Kwaoo is a multinational Fiber-to-the-Home (FTTH) Internet Service Provider.
We provide services to tens of thousands of residential & business customers over public FTTH networks throughout France and Switzerland under the brand names K-net and K-sys, respectively. In 2012, Kwaoo started deploying on their network the SIP softswitch I've been developing since 2006.
I was hired in September 2014 to oversee and deliver continuing development, planning, deployment, tier-3 support, and overall VoIP vision for the company.
I work closely with the engineering teams responsible for data, web, TV, ... development, with the tier-1 and tier-2 support teams, and with our carriers.
