Cellular Network Infrastructure » EPC - Evolved Packet Core » osmo-ePDG - VoWifi Evolved Packet Data Gateway

The osmo-epdg development has reached its first release: 0.1.0.

osmo-epdg is combined ePDG and AAA to support Voice over Wifi (VoWiFi) 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

Thanks a lot to NLNet for funding development of this project.
