Hi Shawn_S , VoLTE is a customized software feature for ISP.

Please refer the information from Zyxel global website.

Hi Support, what does this mean "VoLTE is a customized software feature"?

I would like to know whether the Zyxel LTE3316-M604 supports VoLTE for the provider Telefonica O2 in Germany, or not.
I know that Zyxel LTE3316-M604 supports in principle both voice modes VoLTE (4G) and CSFB (3G), but I am specifically interested in the VoLTE mode for simcards from Telefonica O2 Germany.

If service provider have support VoLTE also ask Zyxel support it in firmware. Then it may have their separate firmware support VoLTE for provider Telefonica O2.
LTE3316-M604 not supports VoLTE for Telefonica O2 in Germany.
