http://opalvoip.svn.sourceforge.net/viewvc/opalvoip/opal/trunk/include/opal/connection.h?revision=25298&view=markup, 
line 1241, shows that InBand is available too in opal, hence it is just 
to enable it in ekiga.  I will do it.

The sending is done in opal, file src/sip/sipcon.cxx.  Please post the 
same message on <opalvoip-user lists sourceforge net>.
