* Added check for bridging in misdn_call to avoid setting echocancellation

when 2 mISDN channels are involved and when bridging is set. That lead
  to a kernel panic before under different situations, because we switched 
  about 2 times between hardware bridging and echocancelation
* readded MISDN_URATE variable which got lost before, this should make app_v110
  work again
* fixed typo
