I'd say that the way to choose would be to use the one that makes life easiest for the CDRs to show the transfer. It seems to me that eliminates the first (chain) choice; since the other two would normally have the same actual call-id value, I don't see how the labeling makes much difference. _______________________________________________ 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/
