Struggling to get Temasys plugin to work in IE with Kurento

I posted this issue on the Kurento Google Group but no answer. Posting here hoping someone might be able to help. The link above points to an implementation of kurento that is suppose to work with Temasys.
I am using the Temasys plugin and the updated kurento-utils above that should give me the ability to view video in IE 10. I have verified that the Temasys plug-in is installed. I get the following error:

Type Error: Object does not support this action

on this line of code:

pc = new RTCPeerConnection(configuration);

I am obviously missing something - anyone have any ideas?

Thanks,
Tim
