This however has been a long-standing/recurring issue A few mails and threads in reference: https://lists.ofono.org/pipermail/ofono/2018-September/018514.html https://lists.ofono.org/pipermail/ofono/2019-February/019134.html https://lists.ofono.org/pipermail/ofono/2019-February/019136.html I'd like to see it fixed, and I have been spending some time on things the last few days. but I have not understood yet where exactly this now needs to be added and how. > It might be a firmware issue.
