- send SWITCH_MESSAGE_INDICATE_DISPLAY when ringing (after knowing calle
info
- send call info when receiving SWITCH_MESSAGE_INDICATE_DISPLAY
The send SWITCH_MESSAGE_INDICATE_DISPLAY part doesn't work yet, because
partner channel is locked (have to find out why)
- for incoming calls, go CS_ROUTING only when number is dialed.
CS_HIBERNATE before
- start media when both side have answered
Also:
- send tone for UNALLOCATED_NUMBER and USER_BUSY
- if channel variables are not sufficent to set call info, ask the
partner channel
