Table
19-4: Codec Parameters
Parameter
Description
voip/codec/codec_info/%d/enabled
Determines the codecs that you want to implement and
their priority. Up to five codecs can be configured, where
the first codec (i.e., voip/codec/0/…) has the highest
priority. To make a call, at least one codec must be
configured. In addition, for best performance it is
recommended to select as many codecs as possible.
When you start a call to a remote party, your available
codecs are compared with the remote party's to
determine the codec to use. If there is no codec that both
parties have made available, the call attempt fails. Note
that if more than one codec is common to both parties,
you cannot force which of the common codecs are used
by the remote party's client. If you do wish to force the
use of a specific codec, configure the list with only that
specific codec.
The %d variable stands for the priority:
ƒ
[0] - Disabled
ƒ
[1] (default) - Enabled
Codec Type
[voip/codec/codec_info /%d/name]
Name of the codec. The variable %d depicts the index
number of the codec entry and its priority, where the first
codec (i.e. voip/codec/codec_info/0/name=…) has the
highest priority. The valid codec parameters are:
ƒ
[G722] G.722
ƒ
[PCMA] G.711 A-Law
ƒ
[PCMU] G.711 Mu-Law
ƒ
[G729] G.729
ƒ
[G723] G.723
ƒ
[RTA] (Narrowband Microsoft RT Audio)
ƒ
[RTA_WB] (Wideband Microsoft RT Audio)
For example, voip/codec/codec_info/0/name=G722.
Note: Specific codecs require specific firmware files. For
more information, refer to the Release Notes.
Packetization Time
[voip/codec/codec_info /%d/ptime]
Packetization time - length of the digital voice segment
