[asterisk-users] UK call initiating party hangup control on analog home lines
I suppose this is rather an informative e-mail than a question. However if people had similar experiences or could comment what the differences are in other countries or with business analog lines, it would be interesting. It took me a week until a BT engineer was sent to my home home, since BT tech support was unable to provide information about the problem. Problem: Calling party controls how long the line will stay open once it is connected. Example: When asterisk box receives a call, it answers, perhaps takes a voice message and issues hangup(). If the calling party does not hang up - the line remains connected - i.e. the caller effectively controls the line. Of course the caller pays for it to BT, therefore it is not a problem for BT. On asterisk irc channel I received a reply along the lines "the caller controls the line, it has always been like that in telephony" and also a reply that in Germany it is different. My experience in Latvia is also different - if any party hangs up, the other party hears busy signal and line is disconnected. Kind of makes more sense if you are used to it. I am posting to provide information for people who might be using landlines in UK and become similarly confused. There is very little information about this, I couldn't find it on the web, people on asterisk irc also were at a loss, BT phone support themselves thought this was a fault. It took an engineer to be able to explain that this was a UK PSTN feature by design. This is not asterisk problem - for example asterisk in my case detects remote hangups alright (which usually has been the problem with UK lines and about which there is quite a bit of info on www), and it can hangup properly if it has initiated a call. So a person calling from say Vodafone mobile would have to be careful to actually make sure he/she presses the red button after speaking to my answering machine on Asterisk. Or any answering machine for that matter, since the problem of course is reproducible with any phone. Best wishes, Roberts

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: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of roberts at latnet.lv Sent: Monday, September 15, 2008 6:06 AM To: asterisk-users at lists.digium.com Subject: [asterisk-users] UK call initiating party hangup control on analoghome lines I suppose this is rather an informative e-mail than a question.
