AoIP Speech Codec Configuration for AMR/FR is wrong
Added by laforge about 6 years ago.
Updated about 6 years ago.
Description
3GPP TS 48.008 v 14.2.0 Rel 14 Section 3.2.2.103 states clearly that for FR_AMR, S11, S13 and S15 are reserved and coded as zero. However, OsmoBSC will send them all coded as '1'.

Intrestingly Table 7.11.3.1.3-2: Preferred Configurations for the Adaptive Multi-Rate Codec Types defines a "wider" default. The possible codecs are then limited by 3GPP TS 48.008 v 14.2.0 Rel 14 Section 3.2.2.103 again. Probably because that the codec settings are applicable defaults by the codec itsself but not in GSM. Also the Endianess was indeed wrong.
I corrected both issues and the tests look much better now. I still need to find out what is wrong with HR and AMR-HR.

With a corrected osmo-bsc.cfg (attached) I get a much cleaner result:
BSC_Tests.TC_assignment_codec_fr #Pass
BSC_Tests.TC_assignment_codec_hr #Pass
BSC_Tests.TC_assignment_codec_efr #Pass
BSC_Tests.TC_assignment_codec_amr_f #Pass
BSC_Tests.TC_assignment_codec_amr_h #Pass

The patches are merged and the TTCN3 tests pass in jenkins.
