I mis-spoke in an earlier post about being able to do this with my Raymarine ES128 using the AIS650 and Ray60 VHF. All I have actually seen were emergency test calls on the screen of the MFD and I can not find any way to initiate a non-emergency call on the es128MFD, even with everything Raymarine and talking over the Raymarine SeatalkNG network.

From what I saw in the 0183 DSC sentence, I think this is probably right. I'd be real interested if you are able to confirm.
From the messages, it looks like 0183 can handle distress calls as well as normal calls. But it looks like N2K's DSC PGN only covers distress calls, and that there is no providing in the N2K standard for placing and receiving normal calls with N2K control. I also found a reference to Simrad/B&G's use of proprietary PGNs for their DSC call control between MFD and their VHF. And Furuno's statement that theirs will not work with other VHFs tells me they are using proprietary PGNs too.
Now I'm interested to try DSC call control with 0183 to see how well it actually works. Sounds like it may very well work between vendors.
