Chan_dongle with RasPBX (Asterisk + FreePBX) errors

I have just checked my dongle huawei e1550. The same error.

By the way, I also have problem with outbound calls ( Using chan_dongle causes notices about lost frames and sound issues ).

Did you try to downgrade to Asterisk13? I’m not sure because not use chan_dongle often, but it seems everything worked for me before upgrading
