Is it possible for E23-Xxx to transfer Data and Voice simulteniuosly in 4G/3G modes?

IoT Modules LTE Standard Module
1

Modem EC25-xxx serie plugged via mPICE2USB to Linux OS.

I would like to make voice calls and use Internet resources at the same time.
As for voice calling management and voice ports are used and as for Internet modem port is used, as I suppose.
For 4G - I think it is possible to do so simulteniously, because of VoLTE, if carrier supports it.
But if it doesn’ t.
Or if network mode is 3G.
Is it able to make calls and use data transfer to access Internet and even to send/receive a traffic to/from PBX (for example Asterisk) simulteniously ?
does harware and firmware allow it ?

Hi @CpServiceSPb
In the IMS mode of the 4G network, voice and data services can be initiated at the same time. What is the specific module model and firmware version you are using? Let me confirm whether it supports IMS.

Did you mean VoLTE ?
