Hello, Has anyone used Asterisk for IAX - SIP - H323 Protocol Translation all in the same box and in production? If yes, what have you used for H323 part? I'm not concerned about RTP Passing through the Asterisk Box (except maybe for IAX), and it is not used as an User Agent. I want to know has it worked in a SoftSwitch Situation for Signal Proxy and Protocol Conversion? and if yes, how?! Thanks for your enlightenment, Seysan

IAX2 does not use RTP. Asterisk is always a User Agent. SIP and H.323
channels using RTP will always start out with RTP flowing through the
Asterisk box, and based on my understanding of H.323, it is not possible
to redirect the RTP media to a different endpoint once the channel is setup.

In summary, while Asterisk is in a lot of ways 'like a softswitch', it
is not a softswitch.

Seysan,
I would not reccomend using H323 with asterisk (atleast not ooh323). I found
on tests that it would core dump a few times a day. I had this issue in both
1.4.X and 1.2.X. Have a ook at some Patton boxes.

Dovid

chan_h323 looks pretty good for me. It has some bugs though,
We are working on issue http://bugs.digium.com/view.php?id=9299
we have some progress there
http://voipsolutions.ru/asterisk_segfault_in_chan_h323_under_heavy_load_20080226
I suppose it would be fixed very soon.
