Hi Neil;
I'm very interested in videoswitch, first I want to know what exactly it
does, how do you pretend to control witch video to show, and if you can send
me the link to take a look.
Thanks
Ian Esper

I'll mail you a link off-list. I want to fix a couple of known issues
and do some tidying before making it more widely available. Hopefully
I'll get the time later this week to do it.

Would you tell us what you put in the q931.c of the libpri for making
asterisk accept the SETUP with the 64kb data option ?
Basically what did you modify ?
Thx
H223 Annex B without double headres (H324M level 2).
If you are looking at the UCLA/Samsung h223 simulator i understand that you
think it's not easy, but i have still not found any device (phone or
gateway), that implements annex C.
I use zaptel and a libpri, it would need some modification in order to be
configurable, but hardcoding the q931 setup info is quite easy.

I'm working on ir currentlySo if we want to do it, since it doesn't look
that easy, we better share our knowledge about it.Sergio: In H223, which
annexe is used ?I've found some interesting stuff capable of handling the
H223+245 but I wanted to understand it more and when you look at the ITU,
and it gets into the Golay(24,12) and BCH code, it starts to become more
complicated :)Tell us more about your expiriance: you modified the libpri
for answering correctly the q.931 ? You use /don't use zaptel ? How do you
capture raw data ? cat /dev/zap/12 ? or with an app_zapgrab ?DO you use BRI
or PRI ?
It's good to see that i'm not the only one developping int this subject.
I have been working on an h234M library, i have finished AL1 and AL2 of h223
(level 2 profile), and almost finished the h245 negotiators. I have been
able to establish a videocall between an asterisk box and a motorola phone,
but i'm having problems with the negotiations on other phones.
Are any one of you going to start an open source proyect?
