[SR-Users] dialog module issues (BYE Request issued) when topos is enabled

i am using dialog and topos module. but i have an issue i think with topos module. When topos module is disabled all the call flow works well but when i enable topos module i have this weird behaviour : after Caller sends BYE and complete the call , i receive later a BYE Request issued by the dialog module towards Caller and Callee. Does anyone already had that issue ? modparam("dialog", "enable_stats", 1) modparam("dialog", "hash_size", 1024) modparam("dialog", "rr_param", "oovdlg") modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "db_mode", 0) modparam("dialog", "db_update_period", 30) modparam("dialog", "wait_ack", 1) modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 30) modparam("dialog", "profiles_with_value", "concurrent_calls") modparam("dialog", "end_timeout", 180) modparam("dialog", "default_timeout", 3600) modparam("dialog", "noack_timeout", 90) modparam("dialog", "early_timeout", 300) modparam("dialog", "dlg_extra_hdrs", "X-OOV-Hint: Dlg-hit\r\n") modparam("db_text", "db_mode", 0) modparam("db_text", "emptystring", 0) modparam("db_text", "file_buffer_size", 8192) modparam("db_text", "max_result_rows", 1000) modparam("topos", "storage", "db") modparam("topos", "db_url", "text:///home/sbc/database") modparam("topos", "mask_callid", 0) modparam("topos", "sanity_checks", 0) modparam("topos", "contact_mode", 0)
