Summary:                    [patch] Support for called_party_subaddr, currently
only calling_party_subaddr is supported
Description: 
Looking at q931.c it only has dump_called_party_subaddr
it's missing receive_called_party_subaddr, transmit_called_party_subaddr,
and associated pri_call changes. Maybe more...

The Telecom Specs in NZ suggests that SUB ADDRESS is always on, so doing
"desk to desk" between offices each with an asterisk box over the ISDN
should then be possible, without a whole load of DDI numbers required.

Is there any work beinging done for this?

Adds support for:
  Calling SubAddress transmit (receive was already supported)
  Called SubAddress transmit and receive
  Note: so far only NSAP, not user defined

dialplan code at caller end looks like:
;subaddress
exten => 8695,1,NoOp(${CALLERID(num):-4} callingsubaddr=${CALLINGSUBADDR}
calledsubaddr=${CALLEDSUBADDR})
exten => 8695,n,Set(__CALLINGSUBADDR=1234)
exten => 8695,n,Set(__CALLEDSUBADDR=5678)
exten => 8695,n,DIAL(DAHDI/1/0412345678)

Console output at called end:
< Calling Number (len=12) [ Ext: 0  TON: National Number (2)  NPI:
