Command Reference

milliseconds.
[route-voice-dial] default entity payload-size g729 180
Restore the initial default time that DSP spends assembling a packet in g729 codec
mode in voice dial program view.
[route-voice-dial] undo default entity payload-size g729
View This command can be used in the following views:
■ Voice Entity view
Description This time length may differ by card type. Because voice entities, which are upper layer
relevant, are hardware independent, the upper-layer can only verify whether the
specified value is in the valid range for the applied codec mode. Whether this value is
valid within the range is decided by DSP based on hardware type. If valid, the value
delivered by the upper layer is used; if otherwise, the default value for the codec
mode is used.
If you find that the configured duration does not take effect, first check that the
assigned value is valid for the card type and codec mode.
s
In voice dial program view, you can use the default entity command to
configure global attributes for voice entities, namely the default time that DSP spends
assembling a packet in each codec mode.
