[Kamailio-Users] incorrect tag in ACK message

[Alex Balashov]

Alex,

Are you sure this is not a bug with the other endpoint (the other side 
of the call)?  The end-to-end ACK for the 200 OK would have to originate 
from it and Kamailio would merely be relaying it.  Is it possible that 
it is in fact that UA which is ignoring the To tag in the 200 OK from 
1.1.1.1?
