Mediant 2000
Parameter Description
IPProfile parameter) and Tel Profile (using the TelProfile parameter).
[EnableRekeyAfter181]
Enables the device to send a re-INVITE with a new (different) SRTP key
(in the SDP) if a SIP 181 response is received ("call is being
forwarded"). The re-INVITE is sent immediately upon receipt of the 200
OK (when the call is answered).
 [0] = Disable (default)
 [1] = Enable
Note: This parameter is applicable only if SRTP is used.
[NumberOfActiveDialog
s]
Defines the maximum number of concurrent, outgoing SIP REGISTER
dialogs. This parameter is used to control the registration rate.
The valid range is 1 to 20. The default is 20.
Notes:
 Once a 200 OK is received in response to a REGISTER message,
the REGISTER message is not considered in this maximum count
limit.
 This parameter applies only to outgoing REGISTER messages (i.e.,
incoming is unlimited).
EMS: Transparent Coder
On Data Call
[TransparentCoderOnDa
taCall]
 [0] = (Default) Only use coders from the coder list.
 [1] = Use Transparent coder for data calls (according to RFC 4040).
The Transparent coder can be used on data calls. When the device
receives a Setup message from the ISDN with 'TransferCapabilities =
data', it can initiate a call using the coder 'Transparent' (even if the
coder is not included in the coder list).
The initiated INVITE includes the following SDP attribute:
a=rtpmap:97 CLEARMODE/8000
The default payload type is set according to the CodersGroup
parameter. If the Transparent coder is not defined, the default is set to
56. The payload type is negotiated with the remote side, i.e., the
selected payload type is according to the remote side selection. The
receiving device must include the 'Transparent' coder in its coder list.
Web: IP to IP Application
[EnableIP2IPApplication
]
Enables the IP-to-IP Call Routing application.
 [0] Disable (default)
 [1] Enable
Note: For this parameter to take effect, a device reset is required.
[IP2IPTranscodingMode
]
Note: This parameter is no longer valid and must not be used.
Defines the voice transcoding mode (media negotiation) between two
user agents for the IP-to-IP application. This parameter must always be
set to 1 when using the IP-to-IP application.
 [0] Only if Required = Do not force transcoding. Many of the media
settings (such as gain control) are not implemented on the voice
stream. The device passes packets RTP to RTP packets without any
processing.
 [1] Force = (Default) Force transcoding on the outgoing IP leg. The
device interworks the media by implementing DSP transcoding.
Web: Enable RFC 4117
Transcoding
[EnableRFC4117Transc
oding]
Enables transcoding of calls according to RFC 4117.
 [0] Disable (default)
 [1] Enable
Notes:
 For this parameter to take effect, a device reset is required.
