Hi all, this is my first message to the list, so hello everyone! I work on the NFV/ SDN area as a solution architect. My experience is mainly on the fixed services, so I'm familiar but not an expert on IMS and EPC technologies.
My question is the following: After Apple introducing native Wifi Calling support on the latest iOS releases I was wondering if it might be possible to create a test environment using Clear Water. My main question is on the access side: For wifi calling, the UE discovers the ePDG by DNS, and uses it to setup an IPSec tunnel. So, a full EPC is required to test wifi calling? As far as I understand it is, because the PDG is the only node able to start the tunnel, both from the UE to itself and the GTP one to the PGW. If so, do you know of any suitable open source EPC implementation that could be used? Does anyone have any experiences on this? thanks a lot in advance, Ignacio.
