The spec (Q.931, page 45) clearly states otherwise: 3.4.1 RESTART This message is sent by the user or network to request the recipient to restart (i.e. return to an idle condition) the indicated channel(s). See Table 3-49. The table immediately following this explicitly shows that RESTART IEs may go in either direction, with the only exception being the Display IE (which is network-to-user only). -- Tilghman _______________________________________________ Asterisk-Dev mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-dev To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-dev
