PSTN extension over Ethernet
timgineer:
I need to extend the PSTN from one location to another using ethernet. Can I do this with a Obi-202 and an ObiLine on one end and a Obi-202 on the other end? Any hints on how to configure each end?
Thanks in advance.

Are you just trying to use the cable or are you expecting to use all the Ethernet infrastructure. Switches, etc.
If you are just wanting to use the existing Ethernet cabling then there are adapters available, but you need to be very careful if you are to avoid damaging things and of course the phone signals cannot transverse switches, etc.
azrobert:
I'm doing what you want with an OBi200 and an OBi110. It's an easy setup. You route calls over the OBiTalk network to the other device.
Do you already have the hardware? A lot of people have had problems (echos and static) with the OBiline adapter. I don't know if these problems have been fixed with new firmware. You can also use an OBi212 or an OBi110. The OBi110 doesn't support GoogleVoice. It's available on Amazon.

You need to decide how to identify calls you want to route to PSTN. I use a "9" prefix. Post which numbers (7, 10, 11 or other digits) you want to route and I'll show you how.

Unless you want more than you have written the cheaper Obi200s can be used in place of the OBi202s.

I unfortunately need need to use "all the Ethernet infrastructure".
I have not yet ordered hardware for fear that I would order the wrong thing.
If I have to dial a 9 prefix to dial out, how are incoming phone calls from the PSTN handled?
For extra extra credit (should you want any) is it possible to have an incoming call from the PSTN ring multiple remote OBi200's?
