H.323 Network
Service Select from the drop-down list the name of the H.323
Network Service to handle the call to the destination
endpoint. The default H.323 Network Service is
automatically listed.
Session Profile ID
(E.164) Enter the Session Profile ID in E.164 format (digits
only). Currently, the ID is defined using up to two
digits. If the call originates from H.323, using this
profile ID, the endpoint enters this ID to indicate how
the call is handled by the gateway. In such a case,
the parameters defined for this profile will be used to
handle the call gateway session.
Line Rate Select the multimedia (audio, video or data) transfer
rate in Kbps for the gateway session. Maximum line
rate currently supported is E1 (1920 Kbps).
Transcoding Select from the drop-down list one of the following
options:
Always - The system forces the video transcoding
mode in all the gateway sessions. A video card is
required to support this mode.
When Required - “Smart Video Switching” mode -
the gateway tries to connect the two endpoints in
video switching mode (that is both endpoints use the
same line rate, video protocol and frame rate). On
failure, the gateway will use transcoding to connect
each participant using the participant's highest video
and audio capabilities that can be achieved. A video
card is required for Transcoding.
None - Transcoding is unavailable in this mode. In
such a case, when the two endpoints use different
line rate or protocols they will not be able to connect
or they will connect in Audio Only mode (without
video).
Note: None is the default setting and it should be
used when you do not want to use video
resources for gateway sessions.
