1000 Hz is recommended if you use lot of meetme channels ( and maybe iax trunking ? ) without a hardware timer .

I always compile custom kernels and have been using 1KHz in all my systems which are for anything vaguely interactive. Most of my asterisk systems are 1GHz processors but I have a small handful which are 533MHz and all are working just fine. You're not using a recently kernel then ;-) 2.6.20 offers 300Hz too (supposedly good for video applications) Gordon _______________________________________________ --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
