Two communication parties can communicate normally only if they share some
■
identical codec algorithms. Therefore, when you configure the compression
command, make sure that the devices on both sides share identical codec
algorithms. Otherwise, the call will fail.
The packetization period for different codecs varies with cards and the part
■
related to the upper layer (voice entity) is independent of hardware. Therefore,
the upper layer only verifies the maximum range for each codec. It is up to the
DSP to determine whether the value within this range is valid according to the
hardware type. If yes, the upper layer sends the value. If no, the default value
for the codec is adopted. If you find that a configured packetization period
does not take effect, first check whether the value configured for the card and
codec is valid.
Follow these steps to configure the local POTS entity to play ringback tones:
To do...
Enter system view
Enter voice view
Enter voice dial program view dial-program
Create a POTS entity and
enter POTS entity view
Bind a number template to
the local voice subscriber line
Bind the POTS entity to a
voice subscriber line
Enable the local POTS entity
to play ringback tones
Use the command...
payload-size { g711 | g723 |
g726r16 | g726r24 | g726r32
| g726r40 | g729 }
time-length
description string
shutdown
Use the command...
system-view
voice-setup
entity entity-number pots
match-template
match-string
line line-number
send-ring
Remarks
Optional
20 milliseconds for a G.711
codec, and 30 milliseconds for
G.723, G.726, and G.729
codecs by default.
Optional
No description by default.
Optional
By default, the management
state of the voice entity is up.

Required
By default, no number
template is bound.
Required
By default, the POTS entity is
not bound to any voice
subscriber line.
Optional
By default, the local POTS
entity does not play ringback
tones.
This command is applicable as
long as the line line number
command binds the POTS
entity to a voice subscriber
line rather than FXS voice
subscriber line or FXO voice
subscriber line.
