[Serusers] Call forward on no answer in 0.10

[Maciej Żwirski]

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.
