  Chan_dahdi sends an empty COLP on the bridged channel.
  
  Chan_dahdi always inserts a connected party IE when you call from one
  dahdi channel to another dahdi channel, even if no such information was
  received on the 2nd channel.  This clears the display of many phones.
  
  * Removed leftover artifact from before the valid flag was added.
  
  * Updated all of the channel's caller id information with the new
  connected line information instead of just the string parts.
