maybe I was too blind and didn't see it in GSM 04.08, but setting NECI=1 will not allow us to assign a TCH/F for MO Call.
What about this:
0100xxxx Originating speech call from dual-rate mobile station when TCH/H is sufficient and supported by the MS for speech calls and the network sets NECI bit to 1
At least this is what the Nokia 3310 uses for a voice call. OpenBSC should than allocate a TCH for it.
Best regards, Dieter

True, and our channel allocator will allocate a TCH/F if we have no (free) TCH/H available. Yeah, setting NECI=1 sounds like a possible workaround. I wonder if NECI=1 is set on real networks as well. :)
