I am interested in using a 7206VXR as a Session Border Controller for some of our SIP clients. It is hard finding any documention on the VXR and CUBE, but I have run across some documention that says it supports it. What I want to know is, what exactley do you need as far as hardware, IOS version, particlaur licensing for sessions, etc..etc.. in order to get the VXR to function as a SBC? Anybody ever run a VXR as an SBC. Thanks for your help!
