Newer VoIP Phone Models
If you have one of the newer models of Cisco VoIP Phone (a 78-series or 88-series handset) then you can connect it directly to your home router via an Ethernet cable without the need for a Remote Access Point.
You will also require a Jabber profile in order to log in on the handset, as well as certain server information for the device to know where to connect to the University phone system.
