Is your Hipath 4000 set up to support SIP? Someone will slap me if I'm wrong, but I thought SIP didn't really start taking off in that arena until maybe V4 or V5. You would need to have a STMI board that is set up to provide SIP extensions, and have available SIP ports to assign to the phone. Do you have other SIP things that are already working, or is this your first attempt?
