Announcing UC320W 2.1.5(0) Limited Deployment Release


In several of these realeases you have mentioned the "Open Source tar file"... which parts of the UC320 are open source? Obviously Cisco is using Asterisk internally on the UC320... is the open source part Cisco's modifications to Asterisk? Is there any documentation on this that you could point me to?
