Hello! I have a problem with Avaya Vantage K175. An error occurs every minute. The version is CM 6.3, SMGR 6.3, SM 6.3. Certificates have been updated and reissued. The number is configured as 9641sip. It's possible to make and receive calls, but every minute, an error occurs, and during that time, it's impossible to make or receive calls. The phone has been updated to version 3.1.1.2. The same error occurs on firmware 3.0.0.0.
