I think that's fine - they will most likely be at the same site anyway. In general, if you call Alice, and she has forwarded the call, it should behave as though Alice had made the call. Similarly, if I call Alice and she transfers me, my call should behave as though Alice had made the 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
