Hi, i am using the DS-KV8213 as doorbell and a Fire HD 10 as intercom/bell. I have set up the complet solution with the asterisk add on an sip card with your Add-on: Hikvision SDK for Door Intercoms.
I have the problem that after a while the sip clients become unregistred from Asterisk. When somebody is ringing at door he get the unavailable sound and the Fire HD is not ringing. Do you have similar problems?
First i thought that the Fire HD is disconnecting from wifi and then being unregistred from Asterisk, but it ist always plugged in and the display is always on (through enabled developer options).
