<DIV></DIV>Well I'm working on ir currently<BR>So if we want to do it, since
it doesn't look that easy, we better share our knowledge about
it.<BR>Sergio: In <FONT class=EC_EC_>H223, <FONT class=EC_EC_>which annexe
is used ?</FONT></FONT><BR>I've found some interesting stuff capable of
handling the <FONT class=EC_EC_>H223+245</FONT> 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 :)<BR>Tell us more about
<FONT class=EC_EC_>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/<FONT class=EC_EC_>zap/12 ? or with an <FONT
