
This parameter can include up to 25 indices (i.e., five coders per five
coder groups), where indices 0 through 4 is the default coder group.
Notes:

The coder name is case-sensitive.

Each coder type can appear only once per Coder Group.

The packetization time (ptime) determines how many coder payloads are
combined into a single RTP packet.

The device always uses the packetization time requested by the remote
side for sending RTP packets. If not specified, the packetization time is
assigned the default value.

Only the packetization time of the first coder in the defined coder list is
declared in INVITE / 200 OK SDP, even if multiple coders are defined.

The payload type identifies the format of the RTP payload.

For an explanation on V.152 support (and implementation of T.38 and
VBD coders), refer to ''Supporting V.152 Implementation''
403 on page .

The value of several fields is hard-coded according to common standards
(e.g., payload type of G.711 U-law is always 0). Other values can be set
dynamically. If no value is specified for a dynamic field, a default value is
assigned. If a value is specified for a hard-coded field, the value is
ignored.

If silence suppression is not defined for a specific coder, the value
defined by the parameter EnableSilenceCompression is used.

If G.729 is selected and silence suppression is enabled (for this coder),
the device includes the string 'annexb=no' in the SDP of the relevant SIP
messages. If silence suppression is set to 'Enable w/o Adaptations',
'annexb=yes' is included. An exception is when the remote device is a
Cisco gateway (IsCiscoSCEMode).

File Table Parameters'' 191 on page .
IP Profile Settings Table
This [IPProfile] ini file table parameter configures the IP Profile table. Each IP Profile ID
includes a set of parameters (which are typically configured separately using
their individual, "global" parameters). You can assign these IP Profiles to
tables concerned with call routing rules.
