Hello, I have te following setup: IAX client -----(iax)-----> Asterisk -----(h323)----> Cisco AS5300 At the present moment GSM codec is used betwee IAX client and Asterisk. G729 is used between Asterisk and Cisco AS5300. I am thinking that switching from GSM to G729 between IAX client and Asterisk. I know I need G729 licence at the IAX client, but at the Asterisk side can I make Asterisk pass through G729 to Cisco AS5300. This way I do not have to purchace G729 licence for the Asterisk server only for the IAX client. I wonder how this can be done in Asterisk? For example what should I set in the iax.conf or any other .conf file? Reading some of the post in the mailing list, someone mention Asterisk only support passthrough for G723. is that true?
