We've seen the same behavior since the 1.0.x version and have been unable to track it down. What I can tell you is that we used to peak around 40 calls (SIP/IAX to zap over E1 PRI all using alaw) and SIP would crash. I saw a peak of 97 calls today (216 channels with chanspy accounting for most of the difference) and this is on a single core 3.2Ghz with 1Gb ram. What changed? We got rid of IAX. I can't tell you if this will work for you or not, but my nerves are doing better now that I don't get calls at random hours of the day telling me that "we have no phones". As a side note, inbound ZAP(PRI) would still work, but only to IAX endpoints. _______________________________________________ --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
