Parameter Description
configure voip > sbc settings >
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] = (Default) Disable. 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.
configure voip > sbc settings >
sbc-remove-sips-non-sec-transp
[SBCRemoveSIPSFromNonSecuredTransport]
Defines the SIP headers for which the
device replaces “sips:” with “sip:” in the
outgoing SIP-initiating dialog request (e.g.,
INVITE) 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.
'SBC Fax Detection Timeout'
configure voip > sbc settings >
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.
