Hi all,
I successfully patched sofsip_cli and now it can do something near active
call migration :)
Thanks to the versatility of nua api I could achieve my objective with
little effort.
Basically I call someone, then I kill sofsip_cli and I restart it. I launch
my "reinvite" command and the call continues normally. The called client
don't realize what happened.

If someone is interested in this work please contact me! Now I think I'll
try to apply what I understood to freeswitch...

bye
