- better counting of active B-channels.
- make capicommand(progress) "early-B3" usable for non NT-mode incoming channels as well.
- support early Line-Interconnect (bridge) as soon as both B-channels are up. This bridges B-channels

  the original channel callerid.
- added config 'defaultcid' to set a default caller id which will be
  used if dial option 'd' is specified.
- moved ast_softhangup() out of interface lock
- use correct mutex_init call for interface lock
- when 'o' option is used for overlap dialing, do not send any digits

  as INFO_REQ/Overlap).
