Hello Users, My Setup is like this openser --Registrar asterisk --Callflow using asterisk-b2bua + radius for accounting My Intention was to generate a Acct-Stop Packet when there is a failure of RTP media from one of the UAC's( callee or caller) who is in dialog. so that the Caller will not be charged for Meaning less network problems Because there is no way asterisk knows about failed UAC as he may not send a BYE Packet . i used the following parameters set canreinvite=no; rtptimeout=60 seconds; Still there is no Acct-Stop packet generated until the session expires timer fires which is equal to Session-Timeout value from radius? Can anybody have any idea of handling network problem of his type? Looking forward for suggestions Thanks in advance srinivas antarvedi -------------- next part -------------- An HTML attachment was scrubbed...
