Abstract Abstract
The Web Real-Time Communication [WebRTC] working group is charged to The Web Real-Time Communication [WebRTC] working group is charged to
provide protocol support for direct interactive rich communication provide protocol support for direct interactive rich communication
using audio, video and data between two peers' web browsers. With in using audio, video and data between two peers' web browsers. With in
the WebRTC framework, Session Description protocol (SDP) [RFC4566] is the WebRTC framework, Session Description protocol (SDP) [RFC4566] is
used for negotiating session capabilities between the peers. Such a used for negotiating session capabilities between the peers. Such a
negotiation happens based on the SDP Offer/Answer exchange mechanism negotiation happens based on the SDP Offer/Answer exchange mechanism
described in [RFC3264]. described in [RFC3264].

Table 40: 5.4.3 SDP Answer Table 40: 5.4.3 SDP Answer
5.4.4. Legacy Interop with RTP/AVP profile 5.4.4. Legacy Interop with RTP/AVP profile
In this section, we attempt to provide session descriptions
showcasing inter-operability between a WebRTC end-point and a Legacy
VOIP end-point. The ideas included in here are not fully baked into
the standards and might be controversial in nature. The hope here is
to demonstrate a plausible SDP composition to enchance seamless
inter-operability between the aforementioned communication systems.
In the scenario desribed below, Alice is a legacy end-point which In the scenario desribed below, Alice is a legacy end-point which
sends [RFC3264] Offer with two sets of media descriptions per media sends [RFC3264] Offer with RTP/AVP based audio and video descriptions
type. along with DTLS fingerprint and RTCP feedback information.
One set that correponds to [WebRTC] compliant UDP/TLS/RTP/SAVPF
based audio and video descriptions.
Another set with RTP/AVP based audio and video descriptions for
the legacy Interop purposes.
Also to note, Alice includes session level DTLS information and
media level RTCP feedback information as applicable to both the
sets of media descriptions
On the other hand, Bob being a WebRTC end-point, recognizes accepts On the other hand, Bob being a WebRTC end-point follows the
the media descriptions with RTP/AVP profile. The security and procedures in section 5.1.2 of [I-D.ietf-rtcweb-jsep] and accepts the
feedback requirements for the session are either handled by a Alice's offer for DTLS-SRTP based session with RTCP feedback.

Appendix A. Appendix
A.1. JSEP SDP Attributes Checklist
This section compiles a high-level checklist of required SDP
attributes to be verified against the examples defined in this
specification. The goal here is to ensure that the examples are
compliant to the rules defined in section 5 of the
[I-D.ietf-rtcweb-jsep] specification.
A.1.1. Common Checklist
This subsection lists SDP attributes that mostly apply at the session
level.
o v=0 MUST be the first SDP line
o o= line MUST follow with values '-' for username, 64 bit value for
session id and dummy values for 'nettype', 'addrtype' and
'unicast-address' (such as IN IP4 0.0.0.0)
o o= line MUST have the session version incremented in the cases of
subsequent offers.
o s= MUST be the third line with value '-'.
o t= line MUST follow with values for 'start-time' and 'stop-time'
set to zeroes.
o a=identity line MUST be included at the session level if WEBRTC
Identity is being used.
o a=ice-options:trickle MUST be present at the session level in all
offers and answers when supported.
A.1.2. RTP Media Description Checklist
Following set of checklist items apply to RTP audio and video media
descriptions.
o The media description's port value MUST either be set to dummy
value of '9' or MUST use the port from the default candidate, if
available.
o The media description's proto value MUST be 'UDP/TLS/RTP/SAVPF'
for JSEP offers.
o JSEP answerer MUST support any combination of RTP/[S]AVP[F] for
interoperability scenarios as defined in section 5 of
[I-D.ietf-rtcweb-jsep]
o c= line MUST be the first line in a media description. A dummy
value of 'IN IP 0.0.0.0' is set if there are no candidates
gathered or its value MUST match the default candidate.
o a=mid attribute MUST be in included.
o One of a=sendrecv/a=sendonly/a=recvonly/a=inactive SDP direction
attributes MUST be present.
o a=rtpmap and a=fmtp attributes per primary, retransmission and
forward error correction media format MUST be included.
o a=rtcp-fb lines for each supported feedback mechanism MUST be
included when using RTP with feedback
o a=imageattr can be optionally present for video media
descriptions.
o a=msid line MUST be included for all the media senders identifying
the MediaStreamTrack (i.e when a=sendonly/a=sendrecv attribute is
present).
o a=extmap line identifying the BUNDLE header extension MUST be
present.
o a=extmap lines for other supported RTP header extensions MUST be
included.
o a=rid line 'per encoding' with the direction of 'send' MUST be
included when further constraining the media format or multiple
encodings per media format is needed.
o a=simulcast line MUST be present if there exists more than one
'a=rid' lines for the media senders.
o a=bundle-only attribute MUST be present for media descriptions
that are impacted by various bundle policies (such as max-bundle/
balanced)
o For media descriptions that aren't "a=bundle-only" and that have
unique address, following attributes MUST be present:
* a=ice-ufrag and a=ice-pwd
* a=fingerprint
* a=setup with value 'actpass' in the offers and a value of
'active'/'passive' in the answerer.
* a=dtls-id
* a=rtcp
* a=rtcp-mux
* For offerers requiring RTCP to be multiplexed, 'a=rtcp-mux-
only' line
* a=rtcp-rsize
o a=group:BUNDLE line with all the 'mid' identifiers part of BUNDLE
is included at the session level.
o a=group:LS session level attribute MUST be included wth 'mid'
identifiers that are part of the lip same sync group.
A.1.3. DataChannel Media Description checklist
If a datachannel is required, an 'application' type media description
MUST be included with the following properties:
o Media description's proto value MUST be 'UDP/DTLS/SCTP' in the
JSEP offers.
o An JSEP answerer MUST support reception of
'UDP/DTLS/SCTP'/'TCP/DTLS/SCTP'/'DTLS/SCTP' for backward
compatibility reasons.
o A value of 'webrtc-datachannel' MUST be used for the media
description 'fmt' value.
o a=mid line MUST be present.
o a=sctp-port with SCTP port number MUST be included.
o a=max-message-size MAY be included, if appropriate.
