Parameter Description
Notes:
ƒ
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.
ƒ
The coder name is case-sensitive.
ƒ
Each coder type can appear only once per Coder Group.
ƒ
The packetization time (ptime) determines how many coder payloads are
combined into a single RTP packet.
ƒ
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.
ƒ
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.
ƒ
The payload type identifies the format of the RTP payload.
ƒ
For an explanation on V.152 support (and implementation of T.38 and
VBD coders), refer to ''Supporting V.152 Implementation'' on page
499 .
ƒ
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.
ƒ
If silence suppression is not defined for a specific coder, the value
defined by the parameter EnableSilenceCompression is used.
ƒ
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).
ƒ

File Table Parameters'' on page 273 .
Web: IP Profile Settings Table
EMS: Protocol Definition > IP Profile
[IPProfile] This 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.
The format of this parameter is as follows:
[IPProfile]
FORMAT IPProfile_Index = IPProfile_
ProfileName , IPProfile_ IpPreference ,
IPProfile_ CodersGroupID , IPProfile_ IsFaxUsed *,
IPProfile_ JitterBufMinDelay *, IPProfile_ JitterBufOptFactor *,
IPProfile_ IPDiffServ *, IPProfile_ SigIPDiffServ *, IpProfile_ SCE ,
IPProfile_ RTPRedundancyDepth , IPProfile_ RemoteBaseUDPPort ,
IPProfile_ CNGmode , IPProfile_ VxxTransportType , IPProfile_ NSEMode ,
IpProfile_ IsDTMFUsed , IPProfile_ PlayRBTone2IP ,
IPProfile_ EnableEarlyMedia *, IPProfile_ ProgressIndicator2IP *,
IPProfile_ EnableEchoCanceller *,
IPProfile_ CopyDest2RedirectNumber ,IPProfile_ MediaSecurityBehaviour ,
IPProfile_ CallLimit , IPProfile_ DisconnectOnBrokenConnection ,
IPProfile_ FirstTxDtmfOption , IPProfile_ SecondTxDtmfOption ,
IPProfile_ RxDTMFOption , IpProfile_ EnableHold , IpProfile_ InputGain ,
IpProfile_ VoiceVolume , IpProfile_ AddIEInSetup ,
