### Description

```asn1
h323AttributesVoiceCapabilitySendingMethod OBJECT-TYPE
SYNTAX INTEGER {abbreviated(0), detailed(1)}
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"Indicates how the line constructs the fastStart element and the
terminalCapabilitySet message. This variable applies only to the fastStart
element of the SETUP message. This applies to all the terminalCapabilitySet
messages. This variable applies only to voice capabilities.
abbreviated : In the fastStart element, for each voice capability enabled, the
line sends a forward OpenLogicalChannel structure with the minimum
packetization period and a reverse OpenLogicalChannel structure
with the maximum packetization period.
In the terminalCapabilitySet message, for each voice capability
enabled, the line sends a 'transmit and receive' AudioCapability
structure with the maximum packetization period.
detailed : In the fastStart element, for each voice capability enabled, the
line sends a forward and a reverse OpenLogicalChannel structure
for each packetization period step.
In the terminalCapabilitySet message, for each voice capability
enabled, the line sends a 'transmit and receive' AudioCapability
structure for each packetization period step.
Each voice capability is configured with a minimum packetization period and a
maximum packetization period. The following table explains the concept of
packetization period step.
Voice capability family Packetization period step
======================= =========================
G.711 One packetization period step at every 10 ms between
the minimum and the maximum packetization periods. For
example, if the minimum packetization period is 10 ms
and the maximum packetization period is 30 ms, the
steps are 10, 20 and 30.
G.729 One packetization period step at every 10 ms between
the minimum and the maximum packetization periods. For
example, if the minimum packetization period is 40 ms
and the maximum packetization period is 50 ms, the
steps are 40 and 50.
G.723 One packetization period step at every 30 ms between
the minimum and the maximum packetization periods. For
example, if the minimum packetization period is 60 ms
and the maximum packetization period is 120 ms, the
steps are 60, 90 and 120.
The line can send a maximum of 20 voice capabilities:
- fastStart element: a maximum of 40 openLogicalChannel structures can be
sent in the fastStart element (20 forward openLogicalChannel structures
and 20 reverse openLogicalChannel structures). Each voice capability is
described by one forward and one reverse openLogicalChannel structure.
- terminalCapabilitySet message: a maximum of 20 AudioCapability structures
can be sent in the terminalCapabilitySet message. Each voice capability is
described by one AudioCapability structure.
If more than 20 voice capabilities are enabled by the configuration, only the
first 20 voice capabilities are sent. This restriction only applies to voice
capabilities and it has no impact on the non-voice capabilities."
