Re: [reSIProcate-users] SRTP

[Karlsson <boost.regex@xxxxxxxxx>]

If I want to use reFlow within my project, then should be:

 

1: Pass a class (for example MySocket) to my media layer, for example, it has methods: send(), sendto(); and  recv(), recvFrom();

 These four methods inturn calls Flow:xxxx() functions.

 

2: In my media layer, use mySocket::send()  mySocket::sendto(); mySocket::recv(); mySocket::recvFrom() to send/recv RTP packets.

 

Right ?

 

Thanks

FlowManagerSipXSocket.cxx is in the recon project folder.  This class
is passed to the sipX media layer.  When it has RTP data to send it
will call FlowManagerSipXSocket::write - which inturn calls
Flow::send.  Assuming you have your own RTP stack - you would want to
use the reflow project in order to take the RTP packets generated by
your media engine and turn them into SRTP traffic then send them on a
socket.  Have a closer look at the reflow section on the wiki for more
info.
