Hi,

Yes I know RPID is different in two cases, but is Asterisk who sends two
Invites (with different RPID) and seems that some phones can't handle those
two consecutive Invites.
We've aplied the patch and this issue continues but it seems that the main
problem of deadlock is solved. (with directmedia=update and sipInfo)

Now I'm doing more probes...

Good job!
