[OpenSIPS-Users] Dialog Eror

[Bakko]

Hello,

is there a solution for this error?

ERROR:dialog:dlg_validate_dialog: failed to validate remote contact: 
dlg=[sip:VMB_1002 at 1.2.3.4:5060] , 
req=[sip:1.2.3.4:5080;lr;ftag=51106545;did=b1c.289a4b12;nat=yes]
In-Dialog ACK from 1.2.3.4 
(callid=ZTNmNGQ2MTg0MGYwNGI1ZDQyN2YzNjU3OWE0OGRmNmY) is not valid 
according to dialog

This error appear on the OpenSIPs log each time the request go to 
Asterisk for ACK and BYE.

Asterisk and OpenSIPs on the same server, same IP, different port.

Thank you in advance.

Regards
