Avoid registration to VoLTE network


does anyone know if legato supports a mechanism to prevent the modem from registering to a VoLTE network?

The mobile network contracts for our devices excludes VoLTE usage. Our customer was complaining that our devices are trying to connect to the VoLTE network without a reason.

We only want to use data connection on our AR7594, we actually don’t need audio/voice support. But it looks like the modem is registering to VoLTE automatically.


Hi Flo,
Per understanding the VoLTE feature depends on PRI configuration.
Please check with your Sierra contact.
