It would have come in parts and assembled in HYD
It does the VoIp internally. The only access available is through the RJ-11
Correct. This is why a few years back I opted for a pair of DECT enabled cordless
phones and it was an import from the gulf for 6k odd. You could get a single unit for around 3k.
There is only one brand to consider and that is Panasonic. The trouble is the Indian ones all work on the same 2.4Ghz wifi frequency
DECT works in the 1.85-1.9Ghz frequency

Check the shops for gulf imports, Amazon has nothing at the prices available from five years back. And get one with a backlit display so the number pad is lit too.
A pair is better than one as when the battery dies you can use the other and it is also a backup in case one unit dies for any reason.
