[asterisk-users] Zaptel kernel module load order
Evening, My latest asterisk box is having a difficult problem. It is configured with one TE210P and TDM400P with four FXO modules. I'm running FC6. The TE210P only has a single PRI. When the system boots, it is completely random what order the zaptel modules will get loaded in. Sometimes zttool shows the FXO as the last span, sometimes as the first. When it does load as the first, which happens more often, nothing will initialize properly. When this happens, I have to unload all the zaptel modules, and re-load them over and over again, until the hardware comes up in the correct order. The order it is loaded is in no way related to what order I load the modules on the command line. This problems makes it unlikely that asterisk will start properly if the system is rebooted. Is there something I can do to ensure the modules get loaded in the correct order? Here's my config files, if they will help... # cat /etc/zaptel.conf span=1,1,0,esf,b8zs bchan=1-23 dchan=24 defaultzone=us loadzone=us span=2,1,0,esf,b8zs bchan=25-47 dchan=48 defaultzone=us loadzone=us fxoks=49-52 defaultzone=us loadzone=us # cat /etc/asterisk/zapata.conf [channels] language=en switchtype=national context=incoming faxdetect=none signalling=pri_cpe group=1 echocancel=yes resetinterval=never channel = 1-23 language=en switchtype=national context=incoming faxdetect=none signalling=pri_cpe group=3 echocancel=yes resetinterval=never channel = 25-47 signalling=fxo_ks usecallerid=yes callerid=Fidelity Reserves group=2 threewaycalling=no context=outgoing channel = 49-52 Thanks for any help, /Mitch ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
[asterisk-users] Server Optimization and Load Balancing
I'm hoping to get some guidance on some of our asterisk growing pains. Any help is greatly appreciated.Over the last few months, our call center has grown considerably and we're now experiencing choppy calls and dropped calls under full capacity. We have around a 60/40 outgoing to incoming ratioAt the moment, we've got the following configuration:Asterisk SVN-trunk-r7230All calls recorded to diskExternal mysql server for CDR + IVR operations Dual Xeon 2.8 4GB Ram (Dell)Digium TE210P2 x PRI lines72 Ploycom 301P SIP phones using ulaw codecWe have a second identical server ready to offset some of the load, but we're not sure how to balance the sip phones and configuration files between the two servers. If we balance the sip registrations between the two servers, then there's the issues of both servers having to handle one call via IAX in some situations. What kind of experiences, problems and solutions have y'all had when adding servers to your center?Should we try to have incoming on one server and outgoing on the other?Should we have both servers capable of handling all the IVR operations, so the other server doesn't have to? Should we try to have an identical configuration between both servers and load balance?What kind of general optimizations should we look at to improve network / server performance?Is there a way to easily register each phone with all asterisk servers, and have the phone choose a random server to dial, and then be available as a SIP to each server if it needs to contact it? Is it a bad idea to register all phones with each server instead of distributing registration?-Here's some of the things we're got planned in the next few days:-Make sure we have all audio files in all codec formats to reduce the need for transcoding in IVR -Convert all music on hold from mp3 to native codec formats-Reduce database operations from within extensions.conf-Upgrade switches on each set of desks to midrange enterprise 100MB switches with gigabit uplinks, from SOHO netgear 100MB switches Thanks,/mitch/fidelity reserves ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
