Thanks Don, I have looked at that page and the described problem (when asterisk does not detect remote (calling) party hangup) is exactly the opposite to my case. In my case I learnt that for BT residential analog lines the remote caller is entitled to hold the line open indefinitely, regardless whether I hang up or not. So this seems to be a feature of BT rather than a problem with asterisk.
I do not know whether there are many countries where telco setup is similar. But looking at the page again I discovered a pointer to this very interesting document: Voice Network Signalling and Control http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00800a6210.shtml So cheers, Robert On Mon, 2008-09-15 at 07:44 -0500, Don Kelly wrote: > I don't know what options BT may provide, but check out "calling party > control" on the Asterisk wiki and see if there's something you can do in > your configuration to make it all better: > > http://www.voip-info.org/wiki/index.php?page=Asterisk+Disconnect+Supervision > > --Don > > Don Kelly > PCF Corp > Real Support for your Virtual Office TM > 651 842-1000 > 888 Don Kell(y) > 651 842-1001 fax > > > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > [EMAIL PROTECTED] > Sent: Monday, September 15, 2008 6:06 AM > To: [email protected] > Subject: [asterisk-users] UK call initiating party hangup control on > analoghome lines > > I suppose this is rather an informative e-mail than a question.
