[SR-Users] finally, an open alternative to Viber

[Daniel-Constantin Mierla]

Hello Daniel,

congratulations, glad to see you get it out, quite quickly after meeting 
at Fosdem!

Another thing which is a plus IMO, enforcing TLS to federate (at least 
with sip5060.net), the right way to do it without the burden of mutual 
peering agreements. I was wondering if cacert.org is trusted CA for the 
service -- they provide free certificates, in a community trusted 
fashion. Cacert was also at Fosdem, signing certificates and identifying 
people wanting certificates. It is a convenient CA for many people in 
the open source world.

Thanks also for suggesting Kamailio for TLS interconnect.

Cheers,
Daniel
