3GPP IMS Client
The UCT IMS Client is designed to be used in conjunction with the Fraunhofer FOKUS Open IMS Core. The client has been developed by the Communications Research Group at the University of Cape Town, South Africa. At present the client is still in active development and there are several known bugs. The client supports AKA authentication, and emulates IMS signaling as far as possible. The current version supports voice and video calls (numerous codecs), pager-mode and session-based instant messaging, Presence, an IPtv viewer and an XCAP client.
