Hi all,
A relative noob here, trying to get a VoIP bridge via chan_quectel.
It looks like I am missing a Vodafone UK VoLTE profile - my current firmware version is EC25EUXGAR08A15M1G and the hardware is EC25-EUX.
Where can I get an updated firmware? Or alternatively how can I get the VoLTE working?
