Hi all, This is regarding sending VoIP metrics report for SIP session.In the
metrics report, There are two headers , called CallID and DialogID. Though the
header DialogID is to be filled withthe dialog information of the SIP INVITE
session, all the examples contradicts it.Pl suggest how DialogID header should
be filled. In the below VoIP metric report,why the value of 'Call-ID' header
differs from the 'CallID-Param' of 'DialogID' header?Also, it looks like that
the Call-ID param of DialogID headers, partially matches with the callID of SIP
PUBLISH request.Pl find a sample VoIP metric, that will be carried by a PUBLISH
request,when the call is terminated.
http://tools.ietf.org/html/draft-ietf-sipping-rtcp-summary-10; DialogID
provides the identification of the dialog with; which the media session is
related. This value is taken; from the SIP header.DialogID = "DialogID" COLON
Call-ID-Parm *(SEMI did-parm)did-parm = to-tag / from-tag / wordto-tag =
"to-tag" EQUAL tokenfrom-tag = "from-tag" EQUAL token; CallId provides the
call id from the SIP dialogCallID = "CallID" HCOLON Call-ID-ParmSample VoIP
