BYE message disapearing.
The same not resolved case here:
http://lists.iptel.org/pipermail/serusers/2005-July/021698.html
The source of trouble was in the nat_uac_test parameter 16:
Here is the part of cisco log:
Jul 31 12:16:00.726 UKR: CCSIP-SPI-CONTROL:
act_idle_connection_created: Connid(1) created to 193.28.184.13:5060,

Via header the same in the all availible IOS-es.
As the result openser considerate the Cisco is out of the nat box.
The question is: Can someone show me the case when this parameter is
necessary, before I'll switch it of on the production server?
I am not sure I
got the problem here. Can you send entire sip trace for
such a call? ser/openser does not store dialog state, so the ua should
update details within calls. be sure you can the nathelper contact
update function for ack as well.
