IV. Configuring the codec type used when the gatekeeper initiates capability
negotiation to an office device
When the gatekeeper initiates capability negotiation to a called/calling office device in
the routed call mode, the audio/video/data codec type of the called/calling office device
is required. The gatekeeper fails the capability negotiation if it has not obtained the
codec type that the office device supports. Therefore, you need to configure the
audio/video/data codec type of the called/calling office device.
Note:
Before the configuration, you need to know the audio/video/data codec type of the
called/calling office device. In the configuration, note to configure the same codec type
with both the calling and called devices to make sure successful calls can be made.
Perform the following configuration in LS-OFFICEGROUP-OFFICE view.
Table 1-49 Configure the codec type
Operation Command
Configure the codec type used when the
gatekeeper initiates capability
negotiation to an office device
codec { audio { g7231 | g729 | pcma |
pcmu } [ packet-length
packet-length ] } | { video { h261 |
h263 } } | { data t38fax }
Restore the default codec type undo codec { audio | video | data }
By default, G.729 is adopted for audio codec, the packetization time length is 30 ms,
and video codec and data faxing is not supported.
V. Configuring the default codec type of an office group
For an office device that is not configured with a codec type, the gatekeeper uses the
codec type configured on the office device for capability negotiation.
Perform the following configuration in LS-OFFICEGROUP-PREFIX view.
Table 1-50 Configure the default codec type of an office group
Operation Command
Configure the default codec type of an
office group
codec { audio { g7231 | g729 | pcma |
