Oh im glad to know astlinux is on libata.. Is 1.0.2 on eglibc or still on uclibc? Or is it switchable in the build environment? One of the tricks to making asterisk work in large environments is to manually load your modules and load only the ones you need.. I only load 34 modules for most systems... I also keep running linux processes to a minimum and don¹t allow asterisk to compress for internal calls... In large installations ive been known to set up 'trunking gateways' that will handle compression so the main phone system doesn¹t have to... I also do as much directmedia=yes as I can so that asterisk is out of the calls.. In my installations use of inband call features isnt required so I don¹t need asterisk to remain in the RTP stream.. So I make asterisk as much of just a call-control as possible.. Many customers have traditional T1 or PRI circuits coming in as their trunks.. I find it just as if not more cost effective to toss say an adtran 904 gateway in front of the asterisk rather than a T1 card in the PBX.. The adtran has advanced echo can.. Talks SIP to asterisk and then PRI / T1 to the telco.. With directmedia enabled the phones once calls are established they talk RTP directly.. Call setup doesn¹t take a lot of resources so the high number of simultaneous calls can be obtained easily... -Christopher
