[Asterisk-Users] IAX and Snom200

[Christian Stredicke]

I think Asterisk should have no problem with NAT, even when used with SIP. I
mean just listen for the first RTP packet and send the stream where it comes
from (that's called symmetrical NAT). I think everybody is doing it like
this now and they are selling their stuff for thousands and thousands of
dollars.

 

Well we do try to look over our shoulders. There is a lot of tempting stuff
out there, and making decisions is difficult. At the moment I think it would
be a mistake for us to start another development branch. We simply have too
many open issues with SIP already. We hope to have a great phone (some
day.-) that fits Asterisk pretty good although it's just using SIP.

Certainly there is the NAT issue and this should not be underestimated. Also
IAX allows optimisation of existing bandwidth between Asterisk servers.

The SNOM guys should look over their shoulders at Verbiage who are bringing
an IAX phone to market. I suspect it will have a lot of interest amongst
this community.

We thought about this option. I guess the IAX2 is not the problem. We
believe the real problem will be the user interface.

 

snom would have no problem providing the platform (hardware plus operating
system and stuff like audio), but we simply don't want to open another
development branch (already got enough trouble with SIP.-).

 

I personally think its ok to optimize the SIP interoperability. All that you
can do in IAX can also be done in SIP (or am I making a big mistake here?).

There is the big difference. in that IAX handles NAT much better, esp.
double NAT (security)

I'm not sure if you work for snom, but I'm willing to help out where I can.

Anyone else care to list the differences between SIP and IAX2?

If would be great to get a comprehensive list, Mark or the digium guys ???
