My new house almost getting ready. I decided in earlier stages to have only Cat6 cabling and no normal telephone cabling.
So I’m looking now for a really good switch that supports 10/100/may be 1000 speed with PoE (power over Ethernet).
Secondly, I need to decide for my basic telephony sets and that includes the converter from IP to normal PSTN lines ( FXO ) and some FXS lines for backup in case my IP telephone failed.
For the switch, our market does not like to offer something reasonable, a switch of 24 port GigEthernet with PoE worth around 6000 SAR!!
Amazon is offering make options one of them which I’m going to pick is switch
it will cost me around 700 USD to reach Riyadh! it supports GigEthernet PoE.
For my telephones, I went for a bit cheaper and I’m thinking of this model from polycom
A set of 10 telephones will cost me around 890 USD 
For the FXO/FXS, the only good choice to pick is
which cost around 75 USD , and that’s for only converting one line…
I ‘m planning for 2 PSTN lines… so I might need two.
The remining is going to be the cheapest PC ATOM motherboad with GigEhternet card with 80GB and install TrixBox on it.
Later I will in need to reconfigure the connectivity with my brother Naser in Australia to proxy him again to the new house with the new setup.
When I move in, I will move to the next plan, Opening the door through my IP PBX, IP Cameras, Call paging, call hunting, call forwarded to my mobile, voice recording.
