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.
