Hi All,
I am trying to implement serial forking and am using the
example on voice-systems website as a guide. The problem I am
experiencing is as follows.
Failure route rewrite ruri with the next uri to try and calls route[17]
route 17 performs a lookup("location"), finds the usrloc information
and rewrites ruri, however, when t_relay is called it uses the
original ruri (one before the lookup) to do t_relay.
Another issue I'm experiencing is that when processing call after
failure route, ruri_user_avp. Once i rewrite the uri in failure
route, I have to use the following to manually write a value for
ruri_user_avp. Can someone explain why this is happening?
Thanks in advance for your help!!
