6. Positive Experience & Gaps Our transition to an open-source based communications backend 6 ▪ Replacement was quick, Kamailio’s flexibility help to adapt quickly ▪ On-net voice + PSTN/SMS break-in/-out working well ▪ iOS <> web interworking challenging (=> Homer) ▪ Client-side challenging for dev’s ▪ Open: Production readiness (orchestration, automation, HA, Push) ▪ Modern Programmability of Kamailio stack to be improved Marten Sebastian We are looking forward to discussing with you! 2019-05-07 v4
