+  a   Configure codecs on GERAN (2G). For AMR codecs, the 'mode-set' instructs the 2G RAN to support specific AMR rates. The octet-align has no effect on the 2G RAN side: on AoIP, osmo-msc always uses a fixed octet-align mode, see <future cfg option>. Make sure that an entry matching the AoIP octet-align mode is present; optionally offer AMR alignment conversion to the other call leg by adding another entry in mismatching octet-align mode. For TrFO between TCH/H channels with AMR-FR used on TCH/F and 3G, consider that AMR-HR does not support mode-set 6 nor 7.
+  iu  Configure (inner) AMR codecs on UTRAN. Towards 3G RAN, osmo-msc *always* uses VND.3GPP.IUFP. The codecs configured here need to be AMR or AMR-WB, corresponding to the AMR payload within the IUFP header. The 'mode-set' instructs the 3G RAN to support specific AMR rates. 'octet-align' has no effect on the 3G RAN, but simply offers AMR alignment conversion to the other call leg.

+OsmoMSC(config)# codecs ?
+  a   Configure codecs on GERAN (2G). For AMR codecs, the 'mode-set' instructs the 2G RAN to support specific AMR rates. The octet-align has no effect on the 2G RAN side: on AoIP, osmo-msc always uses a fixed octet-align mode, see <future cfg option>. Make sure that an entry matching the AoIP octet-align mode is present; optionally offer AMR alignment conversion to the other call leg by adding another entry in mismatching octet-align mode. For TrFO between TCH/H channels with AMR-FR used on TCH/F and 3G, consider that AMR-HR does not support mode-set 6 nor 7.
+  iu  Configure (inner) AMR codecs on UTRAN. Towards 3G RAN, osmo-msc *always* uses VND.3GPP.IUFP. The codecs configured here need to be AMR or AMR-WB, corresponding to the AMR payload within the IUFP header. The 'mode-set' instructs the 3G RAN to support specific AMR rates. 'octet-align' has no effect on the 3G RAN, but simply offers AMR alignment conversion to the other call leg.
