Re: [asterisk-users] Performance Issues Degradation After 6 Calls
I figured it out from asteriskguru.org. If you are using kernel 2.6 enter the following command '#make linux26', before doing '#make install'. and also do ./configure. Hope it will help someone else.

That documentation is obsolete. If you refer to Zaptel, check its README instead. For the record: 'make' in Zaptel will do for any kernel version. -- Tzafrir Cohen icq#16849755 jabber:[EMAIL PROTECTED] +972-50-7952406 mailto:[EMAIL PROTECTED] http://www.xorcom.com iax:[EMAIL PROTECTED]/tzafrir ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I am planning on upgrading to Intel Core 2 Duo with a clock speed of 1.8GHZand 2GB Ram. Does anyone have similar situation or advice? Thanks. You don't say how people are calling in+out. If it's via the Internet, then that's where I'd start to look first. If it's via BRI/PRI interface then I'd look at interrupt issues. I'd suggest that the hardware is more than capable if it's set up correctly. But since you mention bandwidth, I'll assume the calls are coming in via that interface - each call will use 80Kb/sec each way (g711). So 5 calls (to make the math easier) is 10 channels of 80Kb/sec each way - so it's only 800Kb/sec each way. Well under your 4Mb limit. However, at 50 packets per second per call (each way), it's 500 packets per second each way - 1000 pps in total... Can your router sustain more than that? Can your ISP deliver more than that? That's where I'd start to look if it's not local hardware issues... Good luck!
