EC25AF does not ring with incoming calls, and does not make calls on multiple attempts

IoT Modules LTE Standard Module

Hello, I need a solution for EC25-AF.
I have several devices that do not make calls to me and when I call the device it does not ring, in some devices after restarting them they work, but after a few days I get the same error.
In others, I have no solution with the restart process

Help with some firmware or commands to solve the incident.
------- EC25AFFAR07A08M4G_01.001.01.001 --------Current firmware.

Thank you so much.

Hi @carlosl
Will the module do any other business in the days you mentioned? Or will it be completely free for a few days?

No, the module spends most of the time in standby, it is for making emergency calls.
I have already tried different telephone companies and with all the SIMs, I have the same result.

I have this same issue with this firmware version. Was there a solution?

Just to track this here in case someone has a similar problem:

I have received the latest firmware from Quectel, but this did not resolve the problem. I do not know whether the OP’s issue was resolved, but the problem continues for me with the firmware I’ve received:

AFFAR07A14M4G_01.003.01.003
VERSION: EC25AFFAR07A14M4G
