CHAPTER68 Configuration Parameters Reference
Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
[ProgressIndicator2IP] You can also configure the feature per specific calls, using IP
Profiles (IpProfile_ProgressIndicator2IP) or Tel Profiles
(TelProfile_ProgressIndicator2IP). For a detailed description of
the parameter and for configuring the feature, see Configuring IP
Profiles or Configuring Tel Profiles.
Note: If this feature is configured for a specific profile, the
settings of this global parameter is ignored for calls associated
with the profile.
[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).
â– [0] = Disable (default)
â– [1] = Enable
Note: The parameter is applicable only if SRTP is used.
configure voip >
sip-definition
settings > number-
of-active-dialogs
[NumberOfActiveDialogs]
Defines the maximum number of concurrent, outgoing SIP
REGISTER dialogs. The parameter is used to control the
registration rate.
The valid range is 1 to 20. The default is 20.
Note:
â– Once a 200 OK is received in response to a REGISTER
message, the REGISTER message is not considered in this
maximum count limit.
â– The parameter applies only to outgoing REGISTER
messages (i.e., incoming is unlimited).
[TransparentCoderOnDat
aCall]
â– [0] = (Default) Only use coders from the coder list.
â– [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.
Note: The parameter is applicable only to digital interfaces.
'Default Release Cause'
configure voip >
sip-definition
settings > dflt-
release-cse
Defines the default Release Cause (sent to IP) for IP-to-Tel calls
when the device initiates a call release and an explicit matching
cause for this release is not found.
