Hi All, As mentioned below, were are trying to develop charging module for kamailio-ims (using ims_dialog). Unfortunately you have removed both event_route[dialog:start] event_route{dialog:end] from the ims_dialog module. Also observed you have currently not provided facility for exporting ims_dialog pseudo-variables https://www.kamailio.org/docs/modules/stable/modules/ims_dialog.html#idp450… We are unable to proceed further and stuckup badly. Kindly suggest a way to get call times. Kindly answer the mail as soon as possible. We are waiting for your reply. Regard, Prasannakumar.
