<div>you also need HW xcode when you want to make conference call between LAN users and WAN users. LAN users come with g711 and WAN with g729... so you need xcode to mix this in one voice stream...</div> <div>u can use PVDMs on 2800/3800 for this...<BR><BR><B><I>"Fedorov, Konstantin" <kfedor@amt.ru></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Hi,<BR><BR>IP phones support g711 and g729 codecs, so the can utilize <BR>both codecs depending on the region settings, for exam <BR>inside region 711, between regions 729.
