<br>
the business of secondary bearers is a bit murky, and so far it is<br>
limited to VoLTE in practical usage, for which use the modems create<br>
it automatically on top of the IMS bearer when an ATD<num>; command is<br>
entered (or equivalent on MBIM/QMI).<br>

I didn't see anything specifically related to QOS/dedicated bearers but it made me wonder if this goal could be accomplished with MM. I am curious if anyone has experience with creating UE Initiated Dedicated bearers with AT commands? Or, more related to the context of this forum, if there are provisions for this configuration within MM.<br>
