PS1, Line 171: 		/* FIXME: AMR codec configuration must be derived from lchan1! */
Thanks for spotting this!

The below call was actually without effect, because it did not assign sc_ptr.

But we also have chosen a speech codec for SCCPlite connections. I'm pretty sure above gsm0808_speech_codec_from_chan_type() should be here, outside the "if AoIP". It means that so far we fail to send the chosen speech codec back to the MSC for SCCPlite connections. It is mandatory for IP based user plane, which we use, so definitely needs to be fixed. See 3GPP TS 48.008 3.2.1.2 ASSIGNMENT COMPLETE. https://osmocom.org/issues/3528
