Hi,

 Can someone assist me with how one would achieve what Michael Jerris suggested: "IAX offers less overhead on rtp, but the same thing can be accomplished with rtp using packetization..."   ...?

 I have done tons of reading on cRTP etc & I must be missing something as there is no obvious stock standard Linux way to achieve what IAX give you?

Kind Regards,

Michael

I find the secure and efficiency claims on IAX to be pretty much a farce.  IAX offers less overhead on rtp, but the same thing can be accomplished with rtp using packetization, as for security, I don't see any credible claim on that.  IAX also forces the program to sort out a ton of audio for different users going to 1 socket, something that a network stack is quite good at when using different ports, but is a lot more work where we are getting the packets.  As for default passwords and users, of course I wouldn't use those in production, those are for you to see how the pieces work together out of the box.  I wouldn't however quickly scrap the entire default config, just read through them and think about what you need and do not.  The extension ranges you use is totally at your discretion.
