For Blind transfers, one new Reference is added to the Refer-To. For Consultative transfers, two new References are added to the Refer-To. CDR records will now contain a new field that will list the References seen on the INVITEs. Applications processing CDR records can then link (backwards) calls together to form a view of the entire call. _______________________________________________ sipx-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-dev Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-dev sipXecs IP PBX -- http://www.sipfoundry.org/
