Hi, Yep, the dialog is created. I put the dialog into DB and see it. Nothing appears in the logs when the timer is reached. I succeed to do the same behaviour with dialog module only and dlg_set_timeout. Looks to do why I want. I'm a bit frustrating about cnxcc because I really don't understand why nothing happen after max_time, but, anyway, it works with dialog only. Regards, Igor.

Also check kamailio logs maybe you try to terminate call for wrong customer id.

My understanding is to use the function like this : $dlg_var(customer_id) = "customer-" + $fU; $var(max_time) = 5; if (!cnxcc_set_max_time("$dlg_var(customer_id)", "$var(max_time)")) Unfortunately, after 5 seconds, nothing happen. I don't even see an error from dialog module. Anyone has a better understanding of the way the module runs? Thank you!
