osmo-epdg a combined ePDG/AAA¶

The osmo-epdg development has reached its first release. osmo-epdg is combined ePDG and AAA to support Voice over Wifi calls.
An ePDG allows a UE to connect over regular wireless networks to an IMS (untrusted non-3GPP network access).

The combined ePDG/AAA is using a modified strongSwan together with osmo-epdg, a daemon written in erlang/OTP.

The osmo-epdg has been tested with open5gs as EPC and kamailio as IMS.
To allow an easy setup of a fully working ePDG/epc/IMS there are ansible playbooks which has been used to create our Hosted ePDG playground
