I have HO with 40 branches connecting to it. We have 1841 router in HO while 1801 in branches. We plan to deploy CUCM. If we dont require conferencing and no anlaog-> digtal vice versa. Now if i plan to use G.729 everywhere, including HO LAN plus Branhces, do i still need DSPs ? I know its usually kept in design that LAN uses G.711 while over WAN its best to use G.729, but that will involve transcoding which in turn requires DSPs. If i use the same codec G.729 throughout, do i still need DSPs ?
Pls clear this
