Dahua VTO2111D-P-S2 firmware

If the bug was fixed in version 4.6, this should also apply to version 4.7, which you can download from the Dahua DACH website via "Herunterladen" --> Firmware.
OK, if you've already tested version 4.7 and the bug is still present, that obviously won't help you. 
However, I do find it a bit strange that version 4.5 has the bug, version 4.6 doesn't, and then version 4.7 has the bug again. How do you know that version 4.6 supposedly doesn't have the bug?
I can only find these 4.6 versions:
DH_VTOXXXXD-G-S2_MultiLang_PN_PAAS_SIP_EMEA_V4.600.0000000.0.R.220813.bin
DH_VTOXXXXD-G-S2_MultiLang_PN_PAAS_SIP_EMEA_V4.600.0000000.2.R.240802.bin
but they seem to be for a different VTO model (Gen.2). I also read in another (German) forum that these 4.6 versions are supposed to contain some bugs.

I'm actually only familiar with version V4.500.0000002.0.R.210812, and that's already from 2021, so it's very old. There's a version 4.300.x available, but I don't think it's for your S2 model. Whether it makes sense to continue using such older versions is another question, but good luck with your search anyway.
PS: If you can't solve the SIP problem, it might be time for a new VTO.

I had considered the Akuvox E12(W) a while ago when I was looking for a replacement for my Amcrest AD110. But since I don't need SIP and the Akuvox was a bit too "exotic" for me, 
I got the Imou DB61i (OEM model of the Dahua DH-DB6I) for €70 at the time via Ali. Even though the Akuvox model offers extensive features according to the technical data.
It was important to me that I could power the video doorbell via a doorbell transformer and that it had Wi-Fi. Unfortunately, I don't have PoE available outside my front door. I can also easily integrate and use the Imou DB61i with Home Assistant, which was also very important to me.
BTW: The original E12 model is apparently no longer available, or rather, it's probably an EOL model. Instead, there's now the successor model, the E12S-2.
