Monitoring service that uses UL listed IP communicator

I've been working w Alarm Relay, but the IP communicator they recommend is not UL listed. Is anyone aware of a monitoring service that uses a UL listed device? Is my insistence on using a UL listed device unwarranted? I've asked them about several UL listed communicators but they aren't really responding. 
 

What mfg system do you have?  If you want full data it has to be a TCP/IP communicator that will interface with the data bus or serial output etc of your system or dial capture the Contact ID.
 
Honeywell, Napco and other mfg's have UL Listed TCP/IP Communicators.  I think DSC may as well.   

We have an OmniPro II from Leviton. 

Alarm Relay will monitor the OmniProII via a TG-1 Express. You can find the UL Certificate of Compliance here:

TG1 is just cellular tho, right?

Correct. I was under the assumption that's what you were looking for, no?

No, I'm looking for internet monitoring w a UL listed communicator. Cell reception is bad, and our landline has tons of radio interference.

Basically we need a communicator that does not connect to the OP2 through the four phone line terminals (if such a device exists) as we think that's how the massive amount of radio interference enters the mix.

Some TCP/IP Communicators have inputs for basic monitoring.  The Napco NL-MOD-UL does and I am sure there are others.  So a relay on the omni could trip the input in an alarm.  No "data" such as zone number/descriptions etc. 
 
Mfg's seem to have moved away from internet monitoring for the more profitable cell reporting.
