IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
authorization mediatype

Enables media authorization, using external PCRF via Rx, of specific media types (present in the SDP of a SIP message) only.
Platform:

ASR 5000
Product:

SCM (P-CSCF, A-BG)
Privilege:

Administrator
Syntax

    [ no ] authorization
    mediatype { application | audio | control | data | message | others | text | video }

mediatype { application | audio | control | data | message | others | text | video }

no

Disables external authorization for the specified media type.
Usage:

As Per 3GPP 29.214V8.5, P-CSCF/A-BG will authorize VOIP calls only for the media types enabled via this command. The P-CSCF/A-BG sends all media information for all supported media types present in SDP in AAR message to PCRF via Rx. For the other (unsupported) media types, P-CSCF will not send media information in AAR.

Be default, media authorization for all the media types is enabled.
Example:
Enables the P-CSCF to authorize calls for audio media types:

    authorization mediatype
    audio

Disables the authorization of calls for audio media types:

    no authorization mediatype audio
