osmo-epdg a combined ePDG/AAA¶

The osmo-epdg has reached its first version. 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 easy setup of an fully working ePDG there are ansible playbooks which has been used to create our "Hosted ePDG playground:https://osmocom.org/projects/osmo-epdg/wiki/Hosted_epdg_playground
