I defined hardware conference bridge resources in a voice gateway, my question is do I had to define transcoding resources in the voice gateway to establish a conference with two ip-phones in the same LAN (g711 region) and one ip phone at a remote site ( g729 region).?.
HW CFB already includes necessary XCODING if you defined several codecs under the dspfarm, if you only defined 1 codec then yes, XCODER is required
read the media resources chapter of SRND to understand all of this
