ASCI: Forward UPLINK RELEASE on dedicated channel to MSC
If the phone is (still) on a dedicated channel, it may release the
uplink in case of a voice group call. It depends on the MSC how to
handle the situation. Currently it releases the call.
Generally the phone is assigned to the VGCS/VBS channel before it
releases the uplink.
