valid SIM
......................................................................
ASCI: Add option to join voice group/broadcast calls without valid SIM
This option must be enabled in the VTY and is disabled by default.
Calls can be joined when service is limited or normal. With that option
enabled, calls can be joined even with invalid SIM.
Talking is allowed when service is normal. With that option enabled,
talking is always allowed. It depends on the network, if it accepts the
talker.
