Chateau 5G – initiate GSM call via script / AT commands?

RouterOS General
1

I have a MikroTik Chateau 5G with a SIM used as a backup WAN.

In my community, the gate opens by calling a specific number (the call immediately returns busy and triggers the gate).

I’d like to automate this from the router (e.g. via script or Home Assistant trigger), but I can’t find any way in RouterOS to initiate a standard GSM voice call.

Is there any supported method to:

  • trigger a voice call from the LTE modem

  • or send raw AT commands (e.g. ATD<number>;) via RouterOS

  • or any workaround?

You can try:
/interface lte at-chat lte1 input="ATD+123456789;"
but I don't think it will work.

What would happen if you send a sms like :
/tool sms send lte1 phone-number="+123456789" message="Open Sesame "

? :astonished_face:

Chateau 5G - there are several revisions with different modems.

In case of R11mL-RG520F, Quectel AT commands manual says how to initiate voice call: ATD<n>[<mgsm>][;]

If number is 1234 then try

/interface lte at-chat lte1 input="ATD1234;"
