Hi Anne,

Thanks for making this resource available.

The descriptions of RedPhone and Ostel seem a bit inconsistent - or
maybe I don't understand the distinction that's being made.

"RedPhone ... encrypts voice communication data sent between two
devices that run this application. However it also becomes easier to
analyze the traffic it produces and trace it back to you, through your
mobile number. RedPhone uses a central server, which is a point of
centralization and thus puts RedPhone in a powerful position (of
having control over some of this data)."

"When using CSipSimple, you never directly communicate with your
communication partner, instead all your data is routed through the
Ostel server. This makes it much harder to trace your data and find
out who you are talking to. Additionally, Ostel doesn't retain any of
this data, except the account data that you need to log in."

It sounds like you're saying the use of a central server is a
disadvantage for RedPhone but an advantage for Ostel - which may be
true, but I don't understand why.

Cheers,
Michael
