The following SDP types and values. Session description: – v=0 – o=(username) (sess-id) (sess-version) IN (addrtype) (unicast-address for UE) – s=(session name) – c=IN (addrtype) (connection-address for UE) [Note 1] – b=AS: (bandwidth-value) Time description: – t= (start-time) (stop-time) Media description: – m=audio (transport port) RTP/AVP (fmt) – c=IN (addrtype) (connection-address for UE) [Note 1] – b=AS: (bandwidth-value) – b=RS: (bandwidth-value) [Note 5] – b=RR: (bandwidth-value) [Note 5] Attributes for media: – a=rtpmap: (payload type) AMR/8000 [Note 6] – a=fmtp: (format) mode-change-capability=2; max-red= (att-field) [Note 7] – a=rtpmap: (payload type) telephone-event [Note 4] – a=ecn-capable-rtp: leap ect=0 [Note 2] – a=rtcp-fb:* nack ecn [Note 2] – a=rtcp-xr:ecn-sum [Note 2] – a=rtcp-rsize [Note 2] – a=ptime:20 – a=maxptime:240 Note 1: At least one "c=" field shall be present. Note 2: Attributes for ECN Capability may be present if the UE supports Explicit Congestion Notification. Note 3: Void. Note 4: a rate may be added to the “telephone-event” separated by “/” (e.g. “telephone-event/8000”) Note 5: The RR value must be greater than 0. The RS value can be any value. Note 6: The AMR channel number shall be “/1” or omitted. Note 7: Values from 0 to 220 are allowed |

The following SDP types and values. Session description: – v=0 – o=- 1111111111 1111111111 IN (addrtype) (unicast-address for SS) – s=- – c=IN (addrtype) (connection-address for SS) – b=AS:37 Time description: – t=0 0 Media description: – m=audio (transport port) RTP/AVP (fmt) [Note 1, 4] – b=AS:37 – b=RS: (bandwidth-value) [Note 5] – b=RR: (bandwidth-value) [Note 5] Attributes for media: – a=rtpmap: (payload type) AMR/8000/1 [Note 1] – a=fmtp: (format) mode-change-capability=2; max-red=220 [Note 1] – a=ecn-capable-rtp: leap ect=0 [Note 2] – a=rtcp-fb:* nack ecn [Note 2] – a=rtcp-xr:ecn-sum [Note 2] – a=ptime:20 – a=maxptime:240 – a=sendrecv Note 1: The value for fmt, payload type (AMR) and format is copied from step 2. Note 2: Attributes for ECN Capability are present if the UE supports Explicit Congestion Notification. Note 3: Void. Note 4: transport port is the port number of the SS (see RFC 3264 clause 6). Note 5: The bandwidth-value is copied from step 2. |
