What is better Keenetic Vox or regular VOIP adapter?

Question

Telephony

Hello.
Has its own PBX based on Asterisk. You need to connect analog radiotelephones (2 bases).
It turns out you need a VoIP adapter. We have for sale: Grandstream HT802, Cisco 122, but then I came across Keenetic Vox for the same money. In fact, this is what you need + a router and goodies. And so a question - than this decision is worse? Or is it better to really take Keenetic?

Answer 1

Take test. Regarding cisco 122, the thing is good, of course, but sometimes it's buggy, it's better to use linksys spa2102, so there are many times fewer problems with them. HT802 is also quite stable. Tell me about vox yourself.
