I actually did call them once when I had connectivity issues with my OP2. This issue was that I was getting "hit or miss" connectivity whenever I tried to connect to my OP2. Prior to calling, I had the cable company ISP technicians thoroughly check out my cable modem/router and to verify that there wasn't any problems with my network. They ran local and remote tests which isolated the issue to the OP2. I then called SA tech support and informed them that the cable techs ruled out a network issue felt that the issue was with the OP2. The SA tech said the problem was a port forwarding problem and thus he could not assist me with the problem. I tried to convince the SA tech to no avail that I didn't believe it was a port forwarding problem because the cable ISP provider assigns static IP addresses to all customers. Thus, there is no need for for me to use external services such as dyndns etc. Also, the cable techs verified that the router was properly set up for redirecting port 4369 to the OP2.
Rather than getting involved in a heated debate with the SA tech, I just politely thanked him for his effort and hung up.
So, for a few weeks after that I tried all sorts of "solutions" to resolve the problem. None of them worked until one day I decided to change the port from 4369 to 4370. Viola, the the OP2 consistently worked without any problems. For some unknown reason port 4369 would not work with the OP2 but when I shut down the OP2 and used port 4369 with a Dahua Dvr or ZoneMinder (

Also, I have posted a request on the Leviton Space forum for information on the latest Omni Link II protocol documents back in December of 2014. A simple Yes or No response would suffice indicating whether or not new protocol documents are available. Nobody from Leviton has responded to my request. Here's the link to my request

Also, most of the other posts on the Leviton Space forum go unanswered. If answered at all, they are answered by other users of the forum not by Leviton technical staff.
Now, I submit my requests for support via email directly to the Leviton technical staff and consider myself extremely lucky if anyone responds.
Finally, I submitted an email request to tech support on February 24th concerning a UPB issue. Still haven't heard anything. Trust me, I'm not holding my breath waiting for a response.
