Syntax

Parameters

sdp_capabilities

Specifies where to search for the SDP property:

• Local—The capabilities of the device for the subscriber.
• Remote—The capabilities of the device for the remote party.
• Common—The capabilities that the local and remote devices have in common.

SDP property

A comma-delimited list of SDP properties. Specify the SDP properties using one of the following methods:

• Generic descriptor

  Syntax: sdp.[option]

  Where:

  option

  Is any name (for example, i) or any keyword (for example, a=ptime)

  Examples using an SDP generic descriptor:

  • where the common sdp.[a=ptime] is numerically equal to 20
  • where the common sdp.[f=hello] is numerically equal to 20
• Media descriptor

  Syntax: sdp.[m.option]

  Where:

  option

  • fmt
  • port
  • numberofports
  • media
  • proto

  Example using an SDP media descriptor:

  • where the local sdp.[m.numberofports] is numerically equal to 2
• rtpmap

  Syntax: sdp.[codec-name(codec-name).rtpmap.OPTION]

  Where:

  codec-name

  Specifies a codec name.

  option

  • payloadtype
  • clockrate
  • encodingparameters

  Examples using rtpmap:

  • where the local sdp.[codec-name(AMR-WB).rtpmap.clockrate] is numerically less than or equal to 16000
• fmtp

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

  Where:

  codec-name

  Specifies a codec name.

  option

  • fmt
  • profile-level-id
  • mode-set
  • packetization-mode
  • Any other parameter to be conveyed

  Example using fmtp:

  • where the local sdp.[codec-name(AMR-WB).fmtp.mode-set] is numerically less than or equal to 4

operator

One of the following:

• greater than or equal to
• greater than
• less than or equal to
• less than
• equal to
• not equal to

For this condition the default is equal to.

value

String.

Description

Compares a numerical SDP property value against a specified number.
