[Sipwitch-devel] Fwd: Re: Sipwitch Secure,P2P

[Steve Murphy]

All the voice packets are P2P and do not go through sipwitch - so it is
not laughable to say that sipwitch enables secure P2P connections
between sip clients - this is exactly what it does.

I think it is wrong to say sipwitch *only* works on the local
network.  You can put sipwitch on a public server and anybody with a
SIP account on that server can call anybody else with a SIP account on
that server. You should be able to achieve this fairly quickly using the
docs provided.  You may run into difficulties if  both SIP clients are
on the same local network and the server is outside . This might lead
you to think that sipwitch can only work on the local network - but the
issue is more a limitation of cheap router boxes that do not allow
local hosts to connect to each other via forwarded ports ( a.k.a.
hairpinning) than a fault of sipwitch.
