[asterisk-users] IAX2 - Separate Signaling and Media?
Greetings all- Here's an odd question. Supposedly, IAX2 now has the ability to operate with signaling and media in separate streams, very much like SIP. I've read about this feature here[1] and there[2], but I have yet to see how to actually implement or test it. There are no options in the iax.conf sample configs with Asterisk. All suggestions welcome, except those telling me to jump off a bridge because separated signaling and media makes IAX pointless when compared to SIP. :-) --Tim -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

IAX2 cannot use a separate signaling and media stream to setup a call, but it *can* optimize a media stream for a bridged call so that the media does not have to make as many hops as the signaling does. The media still moves on the same ports as the signaling packets, using the same protocol. -- Kevin P.

And in that case the options are: transfer=no ; Disable IAX native transfer ;transfer=mediaonly ; When doing IAX native transfers, transfer ; only media stream Well, it depends on what version. The above is from a 1.4 system - earlier systems had notransfer=yes, but not the mediaonly option. -- Cheers, Matt Riddell ___ http://www.venturevoip.com/news.php (Daily Asterisk News) http://www.venturevoip.com/exchange.php (Full ITSP Solution) http://www.venturevoip.com/st.php (SmoothTorque Predictive Dialer) -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

It only does it in a limited way by setting: transfer=mediaonly in iax.conf I've never tried it, but I'd be happy to co-operate on an experiment :-) Tim.
