Hi All
I am just about to install a new VOIP system into our offices.  We are only a small office but reasonably busy and I only need three to five extensions.  I already have the equipment and I am reasonably confident (famous last words!) in installing the system with a SIP line and connected to a normal telephone line for fall back.  I am NOT sure about one area.  First the Hardware

SPA9000
SPA3102
SPA 962/942 Phones

Ok At present my office system consists of a server with SBS2003 with TWO NIC cards one for LAN and one for WAN.  The Workstations and other items are connected via ethernet to a D Link switch which is connected to NIC1 and the NIC 2 Connects to a Draytek Router/ADSL Broadband Phone Line.  Internet access is obviously supplied to the workstations using DHCP.  All works well at the present.

Now what I dont understand is the connectivity of the SPA 9000 and SPA3102 which has a FXO port for the telephone line.  As I only have one telephone line how do i connect theat line to the router AND the SPA3102.

I hope this explains my question

Thanks for any help

Mark

Hi Mark,
I'll attempt to assist you on your question, though I'm not sure what exactly it is.
The 9000 as far as I could see doesn't support POTS fail-over, so if the WAN connection dies, no users will be able to make calls through it.
The 3102 does support automatic fail-over, so if the VoIP connection is not available it should use the POTS service. This can just be done by connecting a cable from the voice port to any phoneline available in the house. So your question: "As I only have one telephone line how do i connect theat line to the router AND the SPA3102." can be answered pretty easely. As the line is being split up for DSL signal and voice anyways, just connect the WAN port of the SPA3102 to the ADSL modem and the voice port to the voice side of the splitter.
Regards,
LucF

Thanks for the response.  You are correct the SPA9000 does NOT support fall over to POTS but the 3102 does not.  I THINK you have answered my query as to where to connect the 3102, my difficulty was because i do not have a 1 NIC setup but a 2 nIC setup so cant just connect everything to the switch Ill try it tomorrow an dlet you know but I think you are right.

Thanks again
Mark
