Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
■ [0] Disable = Device sends the multiple SDP answers
with the same To-header tag, to the SIP entity. In other
words, this option is relevant if the SIP entity does not
support multiple dialogs (and multiple tags). However,
non-standard, multiple answer support may still be
configured by the SBCRemoteMultipleAnswersMode
parameter.
■ [1] Enable = Device sends the multiple SDP answers
with different To-header tags, to the SIP entity. In other
words, the SIP entity supports standard multiple SDP
answers (with different To-header tags). In this case,
the SBCRemoteMultipleAnswersMode parameter is
ignored.
Note: If the parameter and the
SBCRemoteMultipleAnswersMode parameter are
disabled, multiple SDP answers are not reflected to the
SIP entity (i.e., the device sends the same SDP answer in
multiple 18x and 200 responses).
'Remote Multiple Answers
Mode'
sbc-multi-answers
[IpProfile_
SBCRemoteMultipleAnswersM
ode]
Enables interworking multiple SDP answers within the
same SIP dialog (non-standard). The parameter enables
the device to forward multiple answers to the SIP entity
associated with the IP Profile. The parameter is applicable
only when the IpProfile_SBCRemoteMultipleEarlyDialogs
parameter is disabled.
■ [0] Disable = (Default) Device always sends the same
SDP answer, which is based on the first received
answer that it sent to the SIP entity, for all forked
responses (even if the 'Forking Handling Mode'
parameter is Sequential), and thus, may result in
transcoding.
■ [1] Enable = If the 'Forking Handling Mode' parameter
is configured to Sequential, the device sends multiple
SDP answers.
'Remote Early Media RTP
Detection Mode'
sbc-rmt-early-media-rtp
[IpProfile_
SBCRemoteEarlyMediaRTP]
Defines whether the destination UA sends RTP
immediately after it sends a 18x response.
■ [0] By Signaling = (Default) Remote client sends RTP
immediately after it sends 18x response with early
media. The device forwards 18x and RTP as is.
■ [1] By Media = After sending 18x response, the remote
client waits before sending RTP (e.g., Microsoft Skype
for Business environment). For the device's handling of
this remote UA support, see Interworking SIP Early
Media.
'Remote RFC 3960 Support'
sbc-rmt-rfc3960-supp
[IpProfile_
SBCRemoteSupportsRFC3960]
Defines whether the destination UA is capable of receiving
18x messages with delayed RTP.
