Hello there,

I'm using dialog module to send keep alive options to callee and caller in order to detect if dialog still up, but when kamailio generates the OPTION and parse it, gives the following errors:

I'm using the following dialog configuration:

modparam("dialog","db_url", DBURL)

modparam("dialog","db_mode", 0)

modparam("dialog","enable_stats", 1)

modparam("dialog","dlg_flag", DLG_FLAG)

modparam("dialog","profiles_with_value","concurrentcalls")

modparam("dialog", "detect_spirals", 1)

modparam("dialog","dlg_match_mode", 2)

modparam("dialog", "initial_cbs_inscript", 0)

modparam("dialog", "default_timeout", 3600)

modparam("dialog", "send_bye", 1)

modparam("dialog", "timeout_avp", "$avp(s:timeout_dlg)")

modparam("dialog", "track_cseq_updates", 1)

modparam("dialog", "ka_timer", 10)

modparam("dialog", "ka_interval", 30)

I'm also using topoh module.

Anyone can help me to identify if I'm doing the proper configuration?

Thank you for your support

Best Regards
