Hello, A client has asked for Two B channel Transfer capability (known as TBCT or 2BCT, similar to other features such as ECT, RTL and Q,SIG Path Replacement) in a new Asterisk system and so I researched the capability and came up with quite a few gaps in documentation.
>From what I've gathered, the official Digium statement is that is works with DMS100 only, and only in Asterisk 1.4.X : http://kb.digium.com/entry/26/140/ Although in a bugtracker posting with a patch from over two years ago, Matt Fredrickson from Digium says that it works with 5ESS under Asterisk 1.2.X: http://bugs.digium.com/view.php?id=3554 There are also bounties and claims of this feature working on NI2 protocol(although no patches posted) on the voip-info.org Wiki: http://www.voip-info.org/wiki/view/Asterisk+bounty+PRI+2B+channel+transfer+for+NI2+PRI+line http://www.voip-info.org/wiki/index.php?page=Asterisk%20bounty%20PRI%202B%20channel%20transfer As for actually using this feature, you apparently need to add the following lines to the zapata.conf section that you want to be able to use 2BCT: facilityenable = yes transfer=yes To execute the transfer, you need to use the "Transfer" cmd within Asterisk: http://voipinfo.org/wiki/view/Asterisk+cmd+Transfer And according to this post, you can only do 2BCT transfers if the first call is inbound: http://www.mail-archive.com/[EMAIL PROTECTED]/msg25131.html Does 2BCT work with DMS100 and 5ESS right now? Are there people using this in production right now that can shed some more light on exactly how they are using it, and executing the transfers? Any input would be greatly appreciated. Thanks, MATT--- _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
