The alternative gatekeeper list currently managed by H.323 gateway is
replaced by the list in this field. H.323 gateway selects a gatekeeper with
high priority out of the list to perform the RAS registration procedure.
If no response is received from the selected gatekeeper, it selects the
gatekeeper with the next higher priority to perform the RAS registration
procedure; and after the entire alternative gatekeeper list is selected, the
RAS registration procedure is performed with the secondary gatekeeper
or original gatekeeper according to the Figure 29.7.

Codec Negotiation
Codec Negotiation reports multiple codecs, which H.323 gateway can support
in the H.245 capability exchange stage, to a remote H.323 endpoint, so that a
single codec can be selected ultimately in a call establishment stage. Supply of
multiple codecs in the H.245 capability exchange stage increases the
possibility of call establishment. A single dial-peer can have a single codec, or
the codec list having priority. When a H.323 call occurs from a Ubigate
iBG3026, the codec list(or a single codec) related to the selected dial-peer is
delivered to a remote H.323 endpoint via H.245 Terminal Capability Set
message. When a call is received from H.323 endpoint, the codec list(or a
single codec) related to the selected dial-peer is also delivered to a remote
H.323 endpoint via H.245 Terminal Capability Set message.
