[SR-Users] handling BYEs generated by dialog-timeout

Hello! I'm wondering if someone have experience in changing $du on local kamailio generated packets (like BYE generated at the dialog-timeout) I'm trying to manipulate in `event_route[tm:local-request]` with no success. In the end I have it working using the `forward()` function and then using `exit;` but in this case instead of having 2 BYEs , kamailio sends 4 BYEs (2 with original $du, 2 with new $du) this an example : event_route[tm:local-request] { if ($rm == "BYE") { route(SELECT_OUTBOUND_PROXY); forward(); exit; } } I'm using a kamailio proxy on top with no record-route (we want to have multiple instances of proxy that can change ip address). Thanks in advance! Paolo
