Box 7490 als Telefonzugang und 7390 als IP Client

Freetz und Labor ist immer so nee Sache. Ich nutze Freetz nur noch mit den AVM Release, also der offiziellen Fw.

I guess it is solved now, but for the record. I had the same. After days of testing I found out that the source of the problem is reloading the saved settings of the fritzbox.
To be more specific, 1 or 2 of my VPN settings triggered the problems. When I imported them, my box became very unstable and 1 of the visible things was a crash when I got a phone call.
I solved it by first set the box back to factory settings and then using the option to import the settings from another type of fritzbox and skip the import of these specific (faulty?) VPN's settings. My test fritzbox seems to be stable now. (until yet)

Hope this helps somebody with this same issue.

using replace kernel is sometimes a problem for reboots by phonecall, too.

I had this problem by using Fw-Version 6.03 and 06.20
