Change in osmo-bsc[master]: mgcp: Set up Osmux only when AMR codec is selected

pespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bsc/+/29418 ) Change subject: mgcp: Set up Osmux only when AMR codec is selected ...................................................................... mgcp: Set up Osmux only when AMR codec is selected Until now Osmux was selected unconditionally in bss-side CRCX, without checking if the codec was AMR or not. If Osmux use policy is "on", we only want to request Osmux use if AMR codec is selected.
