<div dir="ltr">To be honest I am not sure, I pulled the data from a cacti graph shortly before posting my reply. I imagine it all ended well, as I don't recall hearing complaints on quality. I have noticed the core dump issue mixed with * and SQL a few months ago. We had about 120-150 users in a conference, that seemed to be okay, heard a complaint about a periodic sputter in audio, but nothing to serious. Issues came once the call was done, ~150 users all hanging up at once. SQL was VERY upset with that, causing * to choke. Though I think it was how we handled the deployment to get it up quickly, and may have been able to prevent this, if tested better. <div class="gmail_extra">

I’ve been able to make 1,024 concurrent faxes (which tend to use more resources than audio calls) in the lab. The problem I had was after the faxes were transmitted, things couldn’t keep up and kept dumping core. Two things were going on, (1) the CDR was written to MySQL and (2) a FastAGI script (I use the AGISpeedy PERL package) to write a log entry also to MySQL. I tried switching the CDR’s to sqlite and that seemed able to keep up, except that its concurrency issues were a problem. If MySQL is the problem, I could probably optimize it better, but it doesn’t explain the Asterisk core dumps. It might be related to the number of FastAGI scripts running, I’m not sure at this point.<u></u><u></u></span></p>

</div><div><div class="h5"><p class="MsoNormal"><u></u> <u></u></p><div><p class="MsoNormal" style="text-align:justify">The better question is, maximum number of users (IP Phones) can your hardware support. I have * deployments with 300-600 phones. - works fine. though concurrent calls has never seen more then 244. Also at this point I have to ask, for this to be any concern to you, you must either A, Make tons of internal calls. OR B have multiple T1's/lots of sip channels? <u></u><u></u></p>
