    HiI am running a chat software what has a built in web client and irc server,the makers of this software no longer support it and also it is made with java and with it no longer supported java warnings from .jar are making users stop using our service due to no code signing.The software is exactly what I need but would like if possible for some one to take its features make it in flash so security warnings are not an issue and also build it around and irc server,Important, the irc server it uses is not unreal or any other it has its own unique one designed for the chat interface,I can let you look over my current website chat so you can see how it works or if you understand what I do not on how a irc server is made to allow irc clients and web applet then that is also fine

    Dear friends, I need someone with VOIP skills in order to finish an VOIP project. I will explain in few words what exactly this VOIP specialist should do: In this moment I have installed on my server software Free PBX, and I need to finish the configuration in this way: - I need to configurate FREE PBX for calling routes - for this I have 3 FXO operators connected to server using an FXO CARD TDM400 from Digium. - FXO CARD Digium is installed but need to be configurated - to make Trunks - and also calling routes , setup IVR am voice mail. - Regarding calling routes: I have 3 operators: Orange,Vodafone and a local fix provider (for Orange and Vodafone I"m using premicell for connecting them with Digium Card) so for example if I"m calling a orange number the pbx server should automatically use the Orange line,the same thing should be used for Vodafone line,if SIP account want to call a vodafone number,server should automatically use the vodafone line and so on... - Also the Voip system should be reachable from internet,because this client is not in the same location... Waiting your answer,Regards,R.
