<DIV> Does someone know coincidentally the cause for the error message
specified in the Subject?<BR><BR>The following scenario: Snom 360 behind one
rout (wiederrum on a DSL line with static IP address hangs). The Snom has a
private IP, routs accomplishes NAT. STUN and ICE are activated, as SIP haven
5060/udp are firmly used. Detailed packages passed on on haven 5060/udp of rout
to the Snom.<BR><BR>The telephone registers itself as expected, and outgoing
telephone calls can be led problem-free. Detailed telephone calls however do not
function (a call is signaled, which rings then however after 3 time on the
mailbox is sent).<BR><BR>The SIP log shows that the telephone sees the INVITE of
the Registrar, it however in principle with “486 Busy here” answered (that is
then also the reason, why the detailed call is sent on the mailbox). The message
mentioned “Denying call appears contemporaneous id=X reason=unconditional” in
the log, whereby X was so far always a negative, one-digit number.<BR><BR>Does
someone have an idea?</DIV>
