 Hello,

 I was wondering if there is a tool that can create the realtime database
 structure for latest Asterisk version or a web resource/file containing the
 sql scripts. Hope I haven't missed obvious things, I had no luck searching
 on the web, in the wiki I found few pages with bits of sql or table
 structures, like:

 https://wiki.asterisk.org/**wiki/display/AST/SIP+Realtime,**
 +MySQL+table+structurehttps://wiki.asterisk.org/wiki/display/AST/SIP+Realtime,+MySQL+table+structure
 https://wiki.asterisk.org/**wiki/display/AST/ODBC+**Voicemail+Storagehttps://wiki.asterisk.org/wiki/display/AST/ODBC+Voicemail+Storage

 I have several table structures from the Asterisk 1.6, I dug for them in
 the code or found on the web when I wrote the tutorial about integration
 with Kamailio 3.1 (http://kb.asipto.com/**asterisk:realtime:kamailio-3.*
 *1.x-asterisk-1.6.2-astdbhttp://kb.asipto.com/asterisk:realtime:kamailio-3.1.x-asterisk-1.6.2-astdb),
 but hopefully now it is an easy way to get the db structure.

 Thanks,
 Daniel

The busiest server I am managing reaches 120 concurrent channels (with
mixed recording). It is a dual processor, dual core Intel 5150 with 16 GB
of ram and raid sas controller. The load reaches rarely 3.0.
Having to double the number of channels and due to the 100% call
recordings, I'll go with a 16 cores. Memory will not a big issue and so the
disk. 64kbit/s x 200 (even adding the overhead of the SIP and IP) will be
under 20 Mbit/s, so a 100 Mbit/s will be fine.

About UK provider, I can't be of any help... I know very good providers in
Germany and Canada, where I am laying my servers, but none in UK.

 What the minimum Server Specifications do I need to run
 200 concurrent channels at the time with .WAV recording (MixMonitor)?

 It will be connected via VOIP sip account.

 Codec will be ulaw.

 Which UK dedicated server provider do you recommend and how much bandwidth
 do I need?

It is not necessary to use an high performance drive. The bottleneck will
be the processor, not the disk. A single disk can handle ten times the load

A single sata disk will be an unacceptable single point of failure. Get
three disks and get in raid5 configuration. You'll gain in safety and
speed. About the CPU model, I am a bit lazy, check the latest CPU released
from intel or amd (I love amd cpu).

RAID-5 is slower than single disks when it comes to write IOPS (a commit

heavy workloads at all costs unless you are writing sequentially in one
file with write caching enabled.

Once the call hangup/completed it will then move recording file to SATA HDD.

Benny is right, if writes are smaller than the stripe size, there is no
gain in speed in using raid5. Not only, but you can have lower performance
than a single disk.

The ramdisk can be a good idea, but if the load is somewhat constant, you
end only moving the slow write ahead of time. 200 calls at 64kbit/s are
just 1.5 Mbyte/s ... even the slowest disk can accomplish this.

Won't 200 simultaneous calls result in a lot of 'head thrashing' that

The extX family of file systems probably will not be clever enough to
try to unfragment the writes; they will likely all end up in one long
fragmented stream. This is exactly what you want if you do not expect
to actually listen to more than a small fraction of the recordings.

If you do expect to listen to most of the recordings, copying them
after they have been written is a great idea. Especially if you have
an off-peak time where the disk is idle anyway, or by placing them on
RAM-disk if you can afford to lose some.

Frankly I would not worry too much, just use reasonably modern
hardware with support for write barriers, enable write caching, use a
not-too-clever filesystem, and go RAID-1 on just two disks.

You could make a ridiculously fast system with NILFS2 and SSD though...

You want some form of raid for redundancy. I usually go with two 15K SAS
drives in raid 1 or four 7.2k SATA drives in raid 10. Performance between
the two should be similar. With drives being as cheap as they are skip raid
5.

That's how we do it - write to a memory based (ramdisk) disk then write to HDD 
upon call completion.  We haven't tried a SSD but that may be necessary 
depending on your call volumes.

  I've made a call to our elastix server and the call was redirected to the
 voicemail, which the user should leave a message. Intead recording the call
 the service returned a message like Sorry, but the user's mailbox can't
 accept more messages. I'm a little lost in the configs here, what
 parameter should I edit to increase the mailbox capacity or what steps I
 take to 'clean' the mailbox?

  Looking at my voicemail.conf I note this snippet:

 ; Maximum number of messages per folder. If not specified, a default value

 ; (100) is used. Maximum value for this option is .

 ;maxmsg=100

 So in my case max messages is .


 (After a quick glance at the source...)

 If not specified, the limit would be MAXMSG (100) not MAXMSGLIMIT ().
