Hi, we are unable to join two new M900 to our multi-master M700/M900 mixed chain.
It's the first time that we see this red box in the status.
Error: Multi cell master does not support this hardware model. New hardware model is required to join this system.
Previously, when we joined other M900 (we have some M900 added to an existing M700 multi-master), they simply stated that some new features were disabled for compatibility with the M700 chain...
What we can do now? It's really strange, because existing ones and new ones are also on same firmware version 05.01/B0001
This could be due to primary in the system not being an M700, which it needs to be if using a mixed system of M700 and M900: if that's the case and the issue is still there, please raise a ticket in our platform and not here on the forum (use http://helpdesk.snom.com/) and we'll investigate further, this may require some files to dig deeper and we cannot handle it on the public forum.
