OBI110 Disconnect Detection not working on UK PSTN
paulm:
The replacement OBi110 arrived today. Have loaded it up with the UK XML file and it is detecting disconnects. CPC detection still isn't working, but it is detecting the 400Hz tone and going on-hook after a few seconds. It is maybe a bit longer delay than I would like, but I shall probably live with it.
Now have to arrange to send the old one back for a refund.
Thanks to ianobi for the helpful responses!

Sorry to bring up an old subject. I thought it was fixed...

CPC detection still isn't working, but it is detecting the 400Hz tone and going on-hook after a few seconds. It is maybe a bit longer delay than I would like, but I shall probably live with it.
But after spending a little while (well, a couple of months) of slowly getting pbx and ip phone extensions configured and working I tried to get voicemail running today and found the problem has returned. Unfortunately I have no idea at what point the Obi110 stopped detecting disconnects as I wasn't making a point of testing this along the way.
I've done a factory reset and re-loaded the UK XML configuration file...with the same settings that worked when I took delivery of this particular device...but this has not cured the problem. The disconnect tone is still there when the caller hangs up, and I've tried some different changes to the disconnect tone pattern setting on the Obi110 as suggested previously in this thread, but still the Obi110 now consistently fails to detect the disconnect.
Any ideas on how to get disconnect detection back? Alternatively, is there some workaround that I could implement in the PBX? I'm using Raspbx (FreePBX and Asterisk running on a Raspberry Pi).
Any help greatly appreciated.
Thanks, Paul

It seems unlikely that two OBi110s have the same problem. In OBi terms it is now quite an old and proven reliable device. Time to eliminate other factors if possible. If it's not an OBi problem, then it must be some other problem in your setup or a problem with your BT line.
Where your BT line enters your home (the NTTP socket) you can disconnect all of your internal wiring from the external BT line. Try connecting your OBi110 at this point to the BT line and try CPC and disconnect tone functions one at a time from there.
If they are feeling helpful, BT can give you a whopping 800ms CPC. See this article:
http://www.stocksy.co.uk/articles/Networks/how_to_get_disconnect_supervision_on_your_bt_telephone_line/
If they agree to do this, then set your OBi110 CPC to something below 800ms - say 600ms.

Hi Paul,
I have exactly the same problem that you had/have. I have my UK Obi110 set up to forward received calls to a CA based Obi200 using Obitalk. When the originating call goes on hook, the Obi110 doesn't recognize what happened and eventually the 400Hz tone is heard.
Did you ever figure out what was going on?
Tom

How we can use it in the https://mobile-spy-apps.com/ mobile recorder on Android?
