I am in the UK and recently got an OBI110. As others have noticed although it may be named the UK version, it still comes with default settings for the US. So I changed the settings as describe at
http://www.obitalk.com/forum/index.php?topic=5866.0The other change I made to the line connection than that listed above is to turn off the silence detection for line disconnect, mainly as sometimes if one has to hold the line may be quiet (either because the other end has no actual hold on their phone so they have just placed the reciever on the desk while they find out information or on very rare occasions the hold system has no music or tones) and I don't like the idea that the OBI110 might disconnect in that situation.
The device seems to work fine except for one small issue. The OBI110 does not seem to detect or pass on the disconnection of the BT PSTN line to the phone, it seems to rely upon the phone disconnecting.
I noticed this with my answer phone, which when connected directly to the BT socket will stop recording immediately when the person hangs up and it does not play the "Thank you for leaving a message" message. However when connected to the OBI110 my answer phone continues to record the disconnect tone and then after quite a few seconds will play the "Thank you for leaving a message" message. I know that the OBI110 is capable of letting my answer phone know of a disconnection as when a message is left on the answer phone from a call coming from my SIP account, it does stop recording immediately upon disconnection (in the same way as I described for the answer phone connected directly to the BT socket).
Any thoughts on what needs changing? I imagine it will be a setting for the PSTN line as I said the phone connection seems to work fine when recieving a SIP call, I just cannot work out what setting needs changing.
