Not without additional hardware/software. You need something that 1.) has a programmable web interface and 2.) can talk to the elk via it's TCP api. You could, for example, set up an HTTP trigger in CQC that would run commands against the Elk, or possibly do something with the webserver addon to run a rule on the ISY to send Elk commands, or setup your own web server and write a javascript or other scripted solution to talk to the Elk.
