Of course this won't work if you route to the

lookup() with permanent entries in location table. If you really have
such a setup you can try to set a certain flag for this entries and then
do not call set_forward_no_connect().
klaus,
i checked and i'm already calling set_forward_no_connect() when initial
request is forwarded to a tcp contact. however, it seems more tricky to
prevent useless tcp connection attempts for in-dialog requests. for
example, here the UA has gone away when presence server sends a notify
to it:
Indeed, I have not thought about in-dialog requests. I think to prevent
useless TCP connection setups for the in-dialog requests a RR-cookie
needs to be added which tells if caller/callee are customers (and
potential behind NAT). Then, by reading this cookie and is_direction()
it should be possible to find out if set_forward_no_connect() should be
executed.
