Although it's not specifically mentioned anywhere, I believe that a minor issue involving call transfers and Asterisk was fixed (so that when possible the transfer is handled by Asterisk and not looped through the Obihai device, using two channels for the duration of the call. Of course, on transfers between different servers or technologies, e.g. transferring an OBiTALK network call to another Asterisk extension, the call still has to go through the Obihai device, but now if you receive a call that comes from Asterisk and you transfer it to another Asterisk extension, the Obihai device can drop out of the connection and let Asterisk do the work).
