dexter has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-mgw/+/27223 ) Change subject: mgcp_codec: do not differntiate between oe and bwe when comparing codec ...................................................................... mgcp_codec: do not differntiate between oe and bwe when comparing codec AMR that has the payload format bandwith-efficient is the same codec as AMR that has the payload format octet-aligned. Its the same codec, and a comparison of the codec info with the function codecs_same() should return true (=equel).

16 Feb '22

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-upf/+/27220 ) Change subject: contrib: add PFCP cause and IEI string maps ...................................................................... contrib: add PFCP cause and IEI string maps These help to build enums and value_strings using regexes. They are a verbatim copy from 3GPP TS 29.244 version 16.6.0 Release 16, paired with C-compatible and possibly abbreviated name strings.
