<html>Dear,<br /><br />Why to develop another kamailio ?<br /><br />The question is kamailio is handeling the status received from rtpengine but not sharing this status for extra control.<br /><br />Do I need to parse the module code to find where it is ? I ahve seen many people in this forum or dev forum to ask to get extra status and most of the time an update is done.<br /><br />Best Regards,<br /><br /><br />On Wednesday, March 30, 2022 12:05 CEST,
