<div>Hi kamailio users, I'm wondering if there's something

ctually seems not possible (also with db mode) because

I looked at the code and the dialog module just not sets the local
socket fields if there is no match, but loads them from db and all
should be fine, an existing socket will be used if there is a need
to send BYE. What exactly you encointered? There is a warning
message when the local socket is not matched, but it's about
ignoring the socket field, not ignoring the dialog from db.<br>
<br>
Cheers,<br>
