caught in some other task meanwhile ... however, the nat is changed for

200ok for invite goes to old port and is accepted by cisco. Then the ACK
comes from the new port -- pretty strange.
Since the PRACK and ACK do not have contact header, you can try add it.
Might help, although the callee should update its dialog state otherwise
there is not a easy solution.
So:
if(is_method("PRACK|ACK") && !is_present_hf("Contact"))
append_hf("Contact: <sip:$si:$sp;nat=yes>\r\n");
Let me know if works.
Cheers,
Daniel

http://www.ipshka.com/core/Nat.txt I just spend a lot of time to fix a trouble with
Cisco AS5300
(AS5350) 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, local_port 50058
--Skipped---
Jul 31 12:16:00.738 UKR: Sent:
INVITE sip:3039100@193.28.184.13:5060 SIP/2.0
Via: SIP/2.0/UDP 193.28.184.21:5060
From: <sip:2308228@193.28.184.21>;tag=12E601F8-10C7
To: <sip:3039100@193.28.184.13>
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.
