User's Manual 20. Coders and Profiles
Parameter Description
From: <sip:100@A>;tag=tag1
To: sip:200@B;tag=tag2
Call-ID: c2
 Endpoint "tag 3":
SIP/2.0 180 Ringing
From: <sip:100@A>;tag=tag1
To: sip:200@B;tag=tag3
Call-ID: c2
In non-standard behavior (when the parameter is configured to
Disable), the device forwards all the SDP answers with the same
tag. In the example, endpoint "tag 3" is sent with the same tag as
endpoint "tag 2" (i.e., To: sip:200@B;tag=tag2).
 [-1] According to Operation Mode = (Default) Depends on the
setting of the 'Operation Mode' parameter in the IP Group or
SRD table:

B2BUA: Device operates as if the parameter is set to
Disable [0].

Call State-full Proxy: Device operates as if the parameter is
set to Enable [1]. In addition, the device preserves the From
tags and Call-IDs of the endpoints in the SDP answer sent
to the SIP entity.
 [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
[IpProfile_SBCRemoteMultipleA
nswersMode]
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 'Forking
Handling Mode' 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
Defines whether the destination UA sends RTP immediately after it
sends a 18x response.
 [0] By Signaling = (Default) Remote client sends RTP
