Hi, I am trying to dial out from asterisks to a h323 endpoint. But it's not allowing to use g723. How can I get it to work in pass-thru mode. Current scenerio is H323 Ep1=======>Asterisk===>Dial-Out=====>H323Ep2 This works with 711 but not with 723. g723 is there on both the Ep. As H323 Ep1======>Gatelkeeper=========>H323Ep2 works filne with h323. I am using the chan_h323 driver provided with Asterisk. How can I get the g723 to work in pass thru mode.
