Your application is basically 2+1 applications. - A SIP client that can listen-in. Creating a SIP client is not the end of the world, doing it on a web-page - I have no idea, but I would be very interested in this myself as well. - A GUI that display a list of calls. - I will also suggest a stand-alone server that collect the info from FreeSWITCH and distribute it to the web clients - and myself I would write the server in C and use gSOAP to export and create a stand-alone WebService. The point of having a mid-server on ESL or something is that FreeSWITCH then only service one client - and don't get drowned by 100 web clients wanting info. What you describe is a very common interface for Call Centre's etc. Jan _____ From: freeswitch-dev-bounces@lists.freeswitch.org [mailto:freeswitch-dev-bounces@lists.freeswitch.org] On Behalf Of babak yakhchali Sent: 13. juli 2010 17:05 To: freeswitch-dev@lists.freeswitch.org Subject: [Freeswitch-dev] eavesdroping Hi what is the best way to implement a web interface in which all channels are displayed and by clicking on each channel, user could listen to that channel.
