Re: [Serusers] Call forward on no answer in 0.10

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. g-)

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.
