Codec list
With NCUI2, direct media connections from IP phones, trunking gateways or HG
3500/75 gateways associated with networked HiPath 4000 systems can be
terminated on the board. Unlike for IPDA, the codec type for DMC connections is
not selected using classmarks but rather on the basis of a codec list which
provides the relevant partners with information about the codec types supported
and preferred.
HG 3575 supports two codec types: G.711 and G.729
The sequence in which the codec types are named defines the preference. The
type named first is preferred.
In the example, NCUI2 supports G.711 and G.729 but G.729 is preferred. The
audio sample size for G.711 and G.729A is set to 60 ms.
T.38 Fax
The parameter T38FAX cannot be used at the moment because this feature is
not yet supported on NCUI.
The dafault value has been set to NO and cannot be changed to YES. The AMO
shows up a
warning
when trying to change the value to YES.
