Hi!

I would like to use this module for a VoLTE/VoWifi/GSM - SIP gateway/LTE router. I found this line in the specification:

“Digital Audio and VoLTE (Voice over LTE)(Optional)”

Could you please tell me what does this mean?

I would like to use it in Hungary (DIGI provider) with a Raspberry Pi (Zero, 3, 4,…). Have someone any experience with this setup?

Thank you in advance!

Hi,
It is better to contact the Quectel’s local FAE team to support you to test VoLTE function and get information.

Same question not planning on using IOS or DROID anymore… if they do not I know the RADIO can work on the network and then a different HAT will be the solution if they Decided they are DATA cucks only
