I'm currently looking for a SIP video intercom and I found the product "NovoSIP" on the internet which sounds interested but I don't know much about video intercom so I would like to know if someone knows about it or what you think about it ?
The NovoSIP is interesting as its based on the Rpi. But its about 380 Euros (without the Rpi) which is still not particularly cheap.
Any SIP based Door phone will work with Asterisk - some may need a few simple config changes to get working though. So I cant see any reason why the NovoSIP would not be configurable at a basic technical level. The rest is down to the firmware etc... but as most SIP devices do not have wonderfully engineered firmware I would not hold that against the NovoSIP either! Its not clear whether NovoSIP uses Door-Berry but it looks like in principal that would be an option too.
All the best
