1. So I plug my pstn in the obi110 > this forwards my pstn to my voip number without paying for forwarding.
2. So then can I set up the virtual switchboard on the voip number? Then customers can hear this when phoning me?
The OBi110 is capable of this, It is long winded but it works like this:
Caller dials your BT number > OBi110 forwards the incoming BT call to your Voipfone PBX (at no charge) using an existing Voipfone sip account defined in the OBi110 ITSP profile > Caller hears the Voipfone PBX and interacts with it > lets say the caller pressed 1 on the PBX and this was set to ring you, Voipfone PBX sends the call back to your OBi110 and your Motorola phone rings.
However, with normal telephony you can have only one telephone call on one telephone line at once. What this means is, should a second caller call your BT telephone number, they will hear an engage tone! That sucks...

Exactly, there is no monthly charge for this other than the one off fee I mentioned earlier.

Well if the BT inbound call restriction is an issue (and I think it will be) then the SPA112 would be a more suitable choice, it has two phone ports where the OBi110 only has the one. Only way to get around the inbound call restriction would be to forward all BT calls to Voipfone but then you're going to be billed per minute for all calls BT divert.
