### Description
When topos is loaded and dialog is configured to timeout a call by sending BYE to each side, the Route: header is lost and one of the BYEs is not sent to the correct destination.
This problem does not exist when topos is not loaded.
### Troubleshooting
#### Reproduction ``` modparam("dialog", "rr_param", "dv") modparam("dialog", "profiles_with_value", "inbound_call ; outbound_call; timed_call") modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "dlg_flag", 4) modparam("dialog", "send_bye", 1) modparam("dialog", "timer_procs", 1) modparam("dialog", "timeout_noreset", 1) modparam("dialog", "default_timeout", 43200)
$avp(limit) = 15; dlg_manage(); dlg_set_timeout_by_profile("timed_call", "1", "$avp(limit)"); dlg_set_timeout($avp(limit)); set_dlg_profile("timed_call", "1"); ``` #### Log Messages
