I just set up Asterisk 1.4.11 on a FreeBSD 6.2 system, and have been testing
it for the last month or so.
I have a single FXO interface installed to provide timing. The server is a
Compaq DL380G2 with Dual 1GHz Xeon chips and about a Gig of ram.
When I was running Linux, it was a pain to administer, but didn't give me any
grief. Now, I'm having calls not hungup, unexplained asterisk core dumps,
unsuccessful calls, and calls dropped when they are on hold.
All channels are SIP only. No g729, no transcoding, just pure SIP.
I haven't seen a load average greater than 0.3 on this machine. I usually
don't get more than 16 channels at once, and see about 20,000 calls per
month.
I'm thinking I should go back to Linux, but I really would prefer BSD.
Am I doing something wrong here, or is the BSD port just not as reliable?

Tim, I've been running asterisk on FreeBSD for a bit over 3 years now.
The current setup is a 750MHz PIII with 256MB ram and 6.2. The previous
was on a dual 550 Xeon running 4.7. The current one has a single FXO
in it (X101P). Both machines are Dell servers.
I've never had a core dump and the only problems I've had were minor
config issues (the kind that are staring you in the face and you still
don't see them) and changes that my voip provider made that I didn't
catch.
The asterisk version I'm currently running is 1.4.0 (one day I'll get
energetic and upgrade it).
Have you analyzed the core dumps to see why or where it fails?

I'm not much of a programmer, so I haven't taken a crack at it a core dump.
I was trying some creative logging to find patterns though. It looked like it
would get panicky when Meetme rooms closed, or if I did a pickup through a
local channel (pickup was trying to re-invite, even though canreinvite=no),
so I used to direct it through a local channel to get around that.
Putting the Zaptel card in seemed to help a lot.
I haven't had a core dump since I removed the pickup through local, but I'm
still getting erratic behaviour at times.
If I do a sip show channels, I get 100 or more channels, mostly SUBSCRIBE. I
could have 40 for one extension, that only has 7 subscriptions on it.
I have the entire overseas rate table listed as part of the dialplan, which is
fairly large. I would like to move that to a database lookup, but I haven't
figured out how to do the pattern matching with a variable length key (some
country codes are longer than others).
I have 1.4.17 installed on a fresh DL360 (same specs, just fewer drive slots),
and I am debating whether to move everyone to that machine (It would be phone
only), or to rebuild it with Linux.
If everyone else out there has been doing high volume production setups
without issue, I would love to stay with BSD. As far as asking for help with
crashes and strange things, what info is useful to post?
Thanks
-Tim

ook for timing to work correctly with ztdummy. you have to do a few things.
1 cd /usr/local/etc/rc.d and edit the zaptel script. as it is missing ztdummy
in the module loads
on the end of the first line of modules before the " put ztdummy.ko and after
the first " on the next line.
then you have to build a new kernel with the setting "options HZ=1000
once you have done these 2 steps ztdummy should work.
the other issue is you need to streamline your install by disabling modules
you dont need.Look at the modules.conf and learn to disable modules. this
will help lower some resourcec. also if you dont need it do not install h323
and postgress/radious server. its all about stream lining your build.
if you need help with this let me know I can walk you threw this.

Please let us know if you find a cause resolution to some of your
problems. I'm also having some trouble with calls not hung up, both SIP
to SIP and SIP to Zap channels. I haven't experienced your other
problems although we do only about a quarter of your volume. My other
problem has been with asterisk dropping calls because it attempts
changing to g.722 even though it's denied in sip.conf and SIP phones as
an option. That's a nasty one but fairly infrequent.
