Hello, For each incoming or outgoing call, sip hardphones I'm using, turn BLF on and off like this: the first call (after leaving idle status) turns 1st BLF on, the second one turns 2nd BLF and so on, when a call is hanged, its BLF is turn off. My first question is : do you think such behaviour is general ? My 2nd question is : using AMI, how can I tell for a given extension : 1. the number of ongoing calls (both incoming or outgoing ones), 2. classify them by time of creation (so that I can be somehow be certain to tie each call with each BLF) I've seen AMI ExtensionState Action ( http://www.voip-info.org/wiki/index.php?page=Asterisk+Manager+API+Action+ExtensionState) but it won't tell the number of calls. To complete my request, I must add that when I'm requesting an extension ongoing calls listing, I haven't previously issued any request asking Asterisk to notify calls events for that extension. Any hint ? Cheers -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20080118/ba2d3930/attachment.htm
