<div>Dear All,</div>
<div> </div>
<div>I configured some voice gateways in CCM which associated with device pool of region "gateway", and the IP phones are in region "Phone". I also configured the autio codec between these 2 regions is
G.729. Most of the sites work fine with this codec setting, but only one site can't accept this codec, I need to change to G.711 then the call can be estiblished. When I check the configuration in this IOS gateway, there is no any specific codec setting. Does anyone know why this situation happen and how to fix it? Any comment would be grateful, thanks a lot.
