Well deep end, based on your situation, I would
visit this website, purchase the SVMi-E from
them, and benefit from their tech support and
warrenty. I believe they will also be able to
get new software for you as well (which is v2.8
by the way).www.telephonesystemsdirect.com. They sell samsung online and give tech support for the stuff. I dont know if they are or not, but even if they are a little more money than where you were planning on getting it, do not hesitate to pay the difference. I have talked to them befor and they are good guys.
Trust me, you will need the added value of the tech support, there are some real kinks in that product (good ones), that you will need assistance with.
Also like someone said earlier, do away with PCMMC if you are not using an iDCS product.
Post back to tell us what you decide.
