do you remember which kind of channel the phone is requesting? is it really asking for a channel for calls?
Yes, the phone always sets the mask according to this (from the spec):
111xxxxx Originating call and TCH/F is needed, or originating call and the network does not set NECI bit to 1, or procedures that can be completed with a SDCCH and the network does not set NECI bit to 1
This was the same for other phones, not just MTK based phones. NECI was set to 0, however I think that setting NECI to 1 might be the solution for the problem, without the need to change the Very Early Assignment procedure. I have not yet tested this in detail, so I might miss something.
Best regards, Dieter
