acRtpAMRCoderHeaderFormat
Module: AC-MEDIA-MIB
OID (symbolic): AC-MEDIA-MIB::acRtpAMRCoderHeaderFormat
OID (numeric): 1.3.6.1.4.1.5003.9.10.4.1.4.2.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: AMR_CODER_HEADER_DEFAULT_FORMAT=0 - old m factor, each frame contains CRM byte and toc RFC_3267_BUNDLING=1 - single CRM byte followed by toc tables RFC_3267_INTERLEAVING=2 - supported as receivers only. Access: Online. AC INI-Param: AMRCODERHEADERFORMAT
What is acRtpAMRCoderHeaderFormat?
This OID selects the AMR frame header format: 0=legacy with per-frame CRM, 1=RFC 3267 bundling, 2=RFC 3267 interleaving (receive-only). Operators choose 1 for modern RFC 3267 compliance to ensure interoperability with standard AMR endpoints. Format 1 reduces overhead by using a single CRM byte for multiple frames.
