However with EVDO your phone uses 1x for voice and EVDO for data. So there are actually two channels opened up that you phone is currently using.
I had the same issue since I am pretty much in a roam only area where I live. The best thing I can suggest for you is not to use data on the phone while roaming.
Another thing that you can try is look at your phone settings and make sure the your DDTM setting is set to "off" This will allow all voice calls to take priority over data. Data will take priority if it is "on"

thats general cell radio knowledge, i knew that already. when i switch my phone to 1x, no data transfer goes on on my device because 1x is slow as hell so id rather not use it. also, my long key end press is set to kill my data conection and i always make sure my connection is dead if im not using it for battery life purposes
with that being said, when i switching the operation mode for the phone radio from hybrid(1x+Ev) to 1x only, ive found that not resetting after switching modes causes the calls to go straight to vm. this may not be the same issue the op is pointing out, but that is a good point and may work for him, but thats not the root to my issue..
