Hello guys,

I'm using the latest release of vicidialnow.
my server: xSeries 366 4xXeon 3.16 Ghz and 6GB

output of free:

i think PAE is installed in centos-kernel, so where can be the problem?
in bios i see 6 gb ram

i'm not a linux expert, but i found something interesting:


linux kernel in use

Code: Select all

[root@vici ~]# uname -rm
2.6.18-92.el5.vnow i686

i see that there isn't PAE installed

Code: Select all

[root@vici ~]# rpm -qa | grep kernel
kernel-devel-2.6.18-92.el5.vnow
kernel-headers-2.6.18-92.el5.vnow
kernel-2.6.18-92.el5.vnow

can i download and install this kernel?

this download is offline, i found another one
http://www.filesearching.com/cgi-bin/s?q=kernel-PAE-2.6.18-92.el5.i686.rpm&l=en&e=on

I'm a really linux newbie and i was a windows junkie
i see, i've got to learn much about linux

UPDATE:

i just tried to install the kernel on my vmware testmachine and it seems to work.
rpm -ivh kernel...
edit die grub.conf to boot from PAE kernel.

but i'm afraid to do this on my realsystem...
anybody some experience to give me some bravery?

If you install kernel-PAE, make sure that you recompile the zaptel modules or else they will fail to load.

Installing the kernel-PAE has some drawbacks on loaded servers. This can affect the performance of your VicidialNOW system. The default CentOS kernel is set to desktop preemption and 250 hz timing which is not optimize for Vicidial performance.

Another alternative is download the kernel source and recompile it. Just enable high memory support so your system can access more than 3.2 gig of RAM.

Why do you need 6 gig of RAM? How many seats are you running on your server? Do you have other applications running?

we have about 80 seats, but at the moment we use another expensive dialer...if vicidial works fine we perhaps plan to expand vicidial... more and more agents will use vicidial. in the first step, 30 seats are planned.
the server has 4x XEON cpus with HT, virtual 8 CPUs

we use one other application which often querries the vicidial database.

it will be fine when i can use the whole memory if possible.

should i try to install vicibox, i read vicibox supports PAE?
i only have to make a dump of mysql database and reinstall my sangoma card.

what do u mean with recompiling the kernel? i thought the vicidial kernel doesn't support PAE or i am wrong?

That's a pretty good hardware I'd say.

I would actually recommend doing a multi-server setup. It's more flexible than a monolithic server. However, since you already have the hardware then it's a single server for you.

I'm not sure about Vicibox supporting more than 3.2gig of RAM since it's also 32bit. Unless it has been recompiled with support for high memory.

What I recommend is downloading the kernel source and recompiling it with high memory support. You need to do this either on VicidialNOW or Vicibox.

i installed vicibox...pretty nice, i've got 6 gigs
the server was very cheap, 350$ (but used - 2 years old)

when i use multipliserver, i think its best when i buy a second big server for the vicidial database.
i only have to make a dump of mysql
change user cron - allow auth from other server
edit astguicliet config
check from viciserver to connect to tremote db server
anything else?

now vicibox is installed, i think to install asterisk 1.4
http://download.vicidial.com/required-a ... ici.tar.gz
and download the latest zaptel and wanpipe drivers?
i only will to do that becuase many ask why we use asterisk 1.2, its nearly EOL...
have i to do something else?

Yes, ViciBox does support PAE out of the box.

For Asterisk 1.4.21.2 you should be able to just install that with the 1.4 zaptel and libpri right before it, then install Sangoma.

i installed zaptel and libpri, then asterisk.
i made a reboot and asterisk 1.4 was loaded fine.
after that i installed wanpipe 3.2.7.1.
i started the setup for wanpipe and AFTER the configuration of wanpipe (i configured two E1 lines) suddenly the server was down.
i can't ping the server anymore.

tomorrow i will look at the screen of the server (in the serverroom)...and make a reboot...very strange.

i will report

ok, it seems to be a kernel crash while unloading zaptel before stopping wanrouter. the start script was wrong.

now I've got a new problem

i installed vicibox.
then downloaded the following packages
- asterisk-1.4.21.2-vici.tar.gz
- libpri-1.4.10.1.tar.gz
- wanpipe-3.2.7.1.tgz
- zaptel-1.4.12.1.tar.gz
shutdown asterisk and zaptel
at first i installed libpri 1.4 with (make - make install) then
i run ./configure script from zaptel 1.4.12 then make - make install
then the same with asterisk 1.4.21.2 like zaptel
reboot
i can connect to asterisk CLI
(Connected to Asterisk 1.4.21.2-vici currently running on ka-vici-dialer (pid = 5351))
then
install wanpipedriver 3.2.7.1 with ./Setup install
i configured my two 2x E1 lines and added wanrouter with ./Setup install_init to start on boot.
after reboot
wanrouter started, i can connect to CLI, no warnings, no alarms.

but asterisk can't create a ZAP channel when i make a call from my SIP phone. on CLI i can't use commands like PRI or ZAP.

can somebody tell me where i've made a mistake?


EDIT:

i found the error:

when i start asterisk with -vvvvvvvgc
i get the following error:

Code: Select all

[Sep 28 17:19:26] ERROR[19125]: chan_zap.c:7216 mkintf: Unable to get parameters
[Sep 28 17:19:26] ERROR[19125]: chan_zap.c:10593 build_channels: Unable to register channel '1-15'


the big question...why?

the card works with vicidialnow.
ztcfg -vv shows 62 channels configured
zttool shows me no alarms
wanrouter status: 2 connected wanpipes

i think i always use zaptel 1.2 and libpri 1.2. .... ahhhh i'm too stupid to install that :-/

had a client yesterday with similar issues during a vicibox install, there were errors tossed during the vicibox from the web service. chan_zap.so asterisk module (and a bunch of other stuff) was missing. needed a full clean reinstall. with NO errors tossed during installation.

when i recompile asteristk 1.2 it works.

so i mean that zaptel and libpri isn't installed correctly.
i tried to uninstall the old zaptel and libpri but without any success.
so i only installed the newer version and recompiled asterisk 1.4

must be a problem with the installation of libpri and zaptel.
when i install vicibox and configure wanpipe, everything works perfectly.

i make something wrong
