The short answer is no you can't get 32 *concurrent* channels on a 250kbps uplink With G729 as a codec you need around 32kbits per channel including the overheads from the voip protocol and tcp etc, so that would give you around 7 *concurrent* channels. Even with G723 at 20kbits per channel you could get a max of 10-11 concurrent channels. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
