Some of the disconnect cause codes reported by MultiVOIP to the PBX were incorrect. It would possibly show the same kind of cause code for any type of disconnection.

Resolution: Implemented RFC3398 and ITU Q1912.5 recommendations for correct cause code translation over SIP protocol.

This was fixed in firmware version (5.09.06).
