I'm trying to implement a sip server for connecting to from an HTML
sip client(made using sipml5). During my research into doing this I've come across sip over web-sockets which might be useful to me, however, I am unsure if a user agent connecting through sip over web-sockets
to a compatible server would then be able to successfully make a call to some one using an incompatible server(i.e. calling from SIP over web-sockets
to true SIP).
I know webrtc2sip
can be used for connecting to legacy networks but I would rather avoid using another proxy if at all possible. So, is it possible to connect to a compatible SIP
server using SIP
over web-sockets
then make a call from this user agent to another that does not support SIP
over web-sockets
without using a gateway
?
