Hello Neels Hofmeyr, Jenkins Builder, I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/2829 to look at the new patch set (#5). gsm0808: add default speech codec configuration In an AoIP scenario, the speech codec list field specifies the codecs used in the RTP interface. This patch adds a table with default codec configurations that match the codec configurations that are also used on the air interface.
