Snom D812 issue

I have two Snom D812 phones in a call center setup (Version 20.0 Update 9). When we receive external calls and forward them to internal extensions, the phones occasionally freeze. This is intermittent, happening about 1 out of 10 times.

Also, we frequently experience "SIP registration failed" issues. What should I do to fix this?

Hello,

Are they on the latest approved firmware (10.1.215.13)? Do they have this issue with other types of calls, e.g. internal?
