Parameters

name

Enter the encoding name used in the SDP rtpmap attribute. This is a required field. No two media-profile elements can have the same name field value. SILK and opus are supported values as of S-CZ7.3.0.

media-type

Select the type of media used in SDP m lines

• Values:
  • audio
  • video
  • application
  • data
  • image
  • text

payload-type

Enter the format in SDP m lines. No payload type number is assigned for newer, dynamic codecs. For RTP/AVP media-profile elements, this field should only be configured when there is a standard payload type number that corresponds to the encoding name. Otherwise, this field should be left blank. This field is used by the system to determine the encoding type when the SDP included with a session identifies the standard payload type on the m line, but does not include an a-rtpmap entry.

transport

Select the type of transport protocol used in the SDP rtpmap attribute

• Default: RTP/AVP
• Values: " UDP | RTP/AVP

clock-rate

The clock rate in Hz for the SDP/RTP map. Use 8000 for narrowband codecs and 16000 for wideband codecs. If set to 0, the default clock rate for the codec will be used.

• Default: 0
• Values: Min: 0 | Max: 4294967295

req-bandwidth

Enter the total bandwidth in kilobits that the media requires

• Default: 0
• Values: Min: 0 | Max: 999999999

frames-per-packet

Enter the number of frames per RTP packet. This field is used to specify a media profile to facilitate Slow Start translations to Fast Start. A value of 0 means that this field is not being used.

• Default: 0
• Values: Min: 0 / Max: 256

parameters

Enter any additional information for codecs

average-rate-limit

Enter the maximum speed in bytes per second for a flow that this media profile applies to

• Default: 0
• Values: Min: 0 / Max: 125000000
• Values: Min: 8192 / Max: 125000000 - Applicable only for SD5 platforms - 4600/6300/6350

peak-rate-limit

Enter the flowspec parameter r (bucket rate) / p (peak rate) value to insert into COPS message for RACF/PDP configuration

• Default: 0
• Values: Min: 0 / Max: 125000000
• Values: Min: 8192 / Max: 125000000 - Applicable only for SD5 platforms - 4600/6300/6350

max-burst-size

Enter the flowspec parameter b ( bucket depth) / m (minimum policed unit) / M (maximum datagram size ) value to insert into COPS message for RACF/PDP configuration

• Default: 0
• Values: Min: 0 / Max: 125000000
• Values: Min: 8192 / Max: 125000000 - Applicable only for SD5 platforms - 4600/6300/6350

sdp-rate-limit-headroom

Specify the percentage of headroom to be added while using the AS bandwidth parameter while calculating the average-rate-limit (rate limit for the RTP flow)

• Default: 0
• Values: Min: 0 / Max: 100

sdp-bandwidth

Enable or disable the use of the AS modifier in the SDP if the req-bandwidth and sdp-rate-limit-headroom parameters are not set to valid values in the corresponding media profile.

• Default: disabled
• Values: enabled | disabled

as-bandwidth

Specifies the value of the AS modifier in the SDP, in kbps, to support bandwidth requirement variation in transcoding scenarios.

• Default: 0
• Values: Min: 0 / Max: 4294967295

police-rate

Enter the rate at which the SBC polices media for external bandwidth

• Default: 0
• Values: Min: 0 | Max: 4294967295

subname

Enter a subname to create multiple media profiles with the same codec name; using a bandwidth value is convenient. For example, you might set a subname of 64k for a media-profile with a name value of PCMU.

standard-pkt-rate

When ptime isn’t available in received SDP for this codec, the SBC uses this default packetization rate baseline to make bandwidth allocations when communicating with an external policy server.

• Default: 0
• Values: Min: 0 | Max: 125000000

Path

media-profile is an element under the session-router path. The full path from the topmost ACLI prompt is: configure terminal , and then session-router , and then media-profile.
