HIKVISION DS-KV8413-WME1(B) says "Calling failed"

[Dreamliner]

System is like that:

• Villa door station HIKVISION DS-KV8413-WME1(B), FW V2.2.53_210907
• 4 Indoor stations HIKVISION DS-KH8350-TE1, FW V2.1.32_210926
• Same PoE Switch for all 5 devices

After installation everything works perfectly, but after some time something went wrong:
I could watch from indoor panels camera of door station, but in case I push call button on door station came voice message "Calling failed".
