Connected and hungup are stored by default in INVITE and BYE records. For the rest: - invite - store the timestamp ($Ts) in an avp when the INVITE comes in main request_route block - alerting - store the timestamp in an avp when 180 response comes in an onreply_route - progress - store the timestamp in an avp when 183 response comes in an onreply_route Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio Advanced Training, Berlin, Nov 5-8, 2012 - http://asipto.com/u/kat Kamailio Advanced Training, Miami, USA, Nov 12-14, 2012 - http://asipto.com/u/katu
