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

Lumicall is now in the Android market - and it fully interacts with
other SIP products using ENUM and SRV records. Any feedback on this is
welcome.
Interconnect (Kamailio calling to/from Lumicall users) is based on the
idea of federated SIP, it is explained at http://www.lumicall.org for
those who want to connect up to it.
Please bear in mind: Lumicall supports ICE (RFC 5245) for NAT traversal,
it is using the ice4j implementation from the Jitsi community. This
makes the SIP packets bigger and often they are too big for the MTU of a
UDP packet. When using ICE, it seems essential to use TLS, to avoid the
MTU problems and also to avoid routers mangling the SIP headers (ICE
doesn't need help from routers, they only confuse the algorithm)
