User's Manual 43. Configuration Parameters Reference
Parameter Description
configure voip > sbc settings >
sbc-remove-sips-non-sec-
transp
when the destination transport type is unsecured (e.g., UDP). (The
“sips:” URI scheme indicates secured transport, for example, TLS.)
 [0] = (Default) The device replaces “sips:” with “sip:” for the
Request-URI and Contact headers only (and retains “sips:” for
all other headers).
 [1] = The device replaces “sips:” with “sip:” for the Request-URI,
Contact, From, To, P-Asserted, P-Preferred, and Route
headers.
CLI: sbc-media-sync
[EnableSBCMediaSync]
Enables synchronization of media between two SIP user agents
when a call is established between them. Media synchronization
means that the media is properly negotiated (SDP offer/answer)
between the user agents. In some scenarios, the call is established
despite the media not being synchronized. This may occur, for
example, in call transfer (SIP REFER) where the media between
the transfer target and transferee are not synchronized. The device
performs media synchronization by sending a re-INVITE
immediately after the call is established in order for the user agents
to negotiate the media (SDP offer/answer).
 [0] Disable = (Default) Media synchronization is performed only
if the RTP mode (e.g., a=sendrecv, a=sendrecv, a=sendonly,
a=recvonly, and a=inactive) between the user agents are
different and synchronization is required.
 [1] Enable = Media synchronization is performed if the media,
including RTP mode or any other media such as coders, is
different and has not been negotiated between the user agents.
 [2] Never = Media synchronization is never performed.
Web/EMS: SBC Fax Detection
Timeout
CLI: configure voip/sbc general-
setting/sbc-fax-detection-
timeout
[SBCFaxDetectionTimeout]
Defines the duration (in seconds) for which the device attempts to
detect fax (CNG tone) immediately upon the establishment of a
voice session. The interval starts from the establishment of the
voice call.
The valid value is 1 to any integer. The default is 10.
The feature applies to faxes that are sent immediately after the
voice channel is established (i.e., after 200 OK).
You can configure the handling of fax negotiation by the device for
specific calls, using IP Profiles configured in the IP Profile table
(see the IpProfile_SBCRemoteRenegotiateOnFaxDetection
parameter in Configuring IP Profiles).
Admission Control Table
Web: Admission Control
EMS: Call Admission Control
CLI: configure voip > sbc sbc-
admission-control
[SBCAdmissionControl]
This table parameter defines Call Admission Control (CAC) rules
for limiting the number of allowed concurrent calls (SIP dialogs).
The format of the ini file table parameter is as follows:
[SBCAdmissionControl]
FORMAT SBCAdmissionControl_Index =
SBCAdmissionControl_AdmissionControlName,
SBCAdmissionControl_LimitType,
SBCAdmissionControl_IPGroupID, SBCAdmissionControl_SRDID,
SBCAdmissionControl_RequestType,
SBCAdmissionControl_RequestDirection,
SBCAdmissionControl_Limit, SBCAdmissionControl_LimitPerUser,
SBCAdmissionControl_Rate, SBCAdmissionControl_MaxBurst,
SBCAdmissionControl_Reservation;
