:-) well, then
a) you don't send off anything because you hit a break/drop somewhere
b) it gets sent, but you are not looking in the right place (right
interface or something...)
try turning up debugging to 5 and see what happens.

I'm not saying that it's wrong. But after this
some call forwarding
should be done and it's not, although I'm calling all the route blocks
and t_relay() does not return any errors...

487 is sent by the UA after a CANCEL is received
and the UA you send
the call to should get a CANCEL from SER when the timer hits. So,
that's not wrong.

Hi,
I've been trying to implement call forward on no answer with the new
ser 0.10. Now I've the following problem. The call times out as it
should, enters the on_failure block, rewrites the address with the
one from database and then goes to the standard route blocks. The
problem is the last sip message being sent (although t_relay doesn't
fail) is the 487 request terminated... Can somebody help me with
this? Below are the parts of my ser.cfg involved. Thanks.
