User's Manual 18. Coders and Profiles
Parameter Description
Web: SBC Remote Delayed Offer
Support
[IpProfile_SBCRemoteDelayedO
fferSupport]
Determines whether the remote endpoint supports delayed offer
(i.e., initial INVITEs without an SDP offer).

[0] Not Supported = Initial INVITE requests without SDP are
not supported.

[1] Supported = (Default) Initial INVITE requests without
SDP are supported.
Note: For this parameter to function properly, a valid Extension
Coders Group ID needs to be configured for IP Profiles that do
not support delayed offer.
Web: SBC PRACK Mode
[IpProfile_SbcPrackMode]
Determines the PRACK mode required at the remote side:

[1] Optional = PRACK is optional for these UAs. If required,
the device performs the PRACK process on behalf of the
destination UA.

[2] Mandatory = PRACK is required for these UAs. Calls
from UAs that do not support PRACK are rejected. Calls
destined to these UAs are also required to support PRACK.

[3] Transparent (default) = The device does not intervene
with the PRACK process and forwards the request as is.
Web: SBC Enforce MKI Size
[IpProfile_SBCEnforceMKISize]
Enables MKI length negotiation for SRTP-to-SRTP flows
between SIP networks (i.e., IP Groups). This feature includes
the capability of modifying the MKI length on the inbound or
outbound SBC call leg, using IP Profiles.

[0] Disable = (Default) Device forwards the MKI size as is.

[1] Enable = Device changes the MKI length according to
the settings of the IP Profile parameter, MKISize.
Web: SBC RFC2833 DTMF
Payload Type Value
[IpProfile_SBC2833DTMFPayloa
dType]
Defines the RFC 2833 DTMF Payload Type for a specific SBC
leg. This enables the interworking of the DTMF payload type for
RFC 2833 between different SBC call legs. For example, if two
entities require different DTMF payload types, the SDP offer
received by the device from one entity is forwarded to the
destination entity with its payload type replaced with the
configured payload type, and vice versa.
The value range is 96 to 127. The default is 0 (i.e., the device
forwards the received payload type as is).
Web: SBC User Registration Time
[IpProfile_SBCUserRegistration
Time]
For a description, see the global parameter
SBCUserRegistrationTime.
