Hello,
i have some issues wth the M300 Base Station and M25.

The M300 is connected our LAN wich is part of a MPLS Network.
There are 2 Firewalls betewen M300 and Internet (no outgoing blocks).
We drive our own SBC with some Sip Accounts in Azure cloud, where the M300 can register there extensions.
I can register several extensions and can see the registration on the SBC.
Some times Incomming and outgoing calls calls are possible, some times not, but there is no understandable reason.

both M300 and M25 have 530.2 Firmware.

I might need some support here to get the devices working.

Best regards
