  • where the common sdp.[u=http] matches one of //www.oracle.com:8080/hr/one.htm
  • where the remote sdp.[xy] matches one of z

• Media descriptor

  Syntax: sdp.[m.option]

  Where:

  option

  • fmt
  • port
  • numberofports
  • media
  • proto

  Where:

  codec-name

  Specifies a codec name.

  option

  • payloadtype
  • clockrate
  • encodingparameters

  Examples using rtpmap:

  • where the common sdp.[ codec-name(AMR-WB).rtpmap] matches one of 104 AMR-WB/160000
  • where the common sdp.[ codec-name(AMR-WB).rtpmap.encodingparameters] matches one of 2
  • where the common sdp.[ codec-name(AMR-WB).rtpmap.payloadtype] matches one of 104,102
• fmtp

  Syntax: sdp.[codec-name(codec-name).fmtp.OPTIONS]

  Where:

  codec-name

  Specifies a codec name.

  option

  • fmt
