antonio,

i read 1.4 code and saw that request uri user is saved to ruri_user_avp
only if next_gw() is called from request route.  so if you call it from
failure_route, it will not be saved, which could explain the above
error.

so if you do local user -> local user -> pstn forwarding, you need to
either route the request back to your proxy and then to pstn, or you
need to call next_gw() in route block before you enter failure route
even when the request is not yet going to a local user.

in 1.5 the implementation is different in that it is possible to call
load_gws() and next_gw() also first time in failure route.
