1. Record Incoming Call On Demand. Record Outgoing Call On Demand
   Extensions in this class:  8001, 8002, 8003, 8004, 8005 (total 5 in number)
2. Record All Incoming Call. Record All Outgoing Call
   Extensions in this class:  9001, 9002, … , 9145 (total 145 in number)

To avoid manual configuration of each extension, I had taken following steps:-

1. Execute following queries on asterisk database (mysql):
   UPDATE asterisk.users SET recording='out=Adhoc|in=Adhoc' WHERE extension IN (8001, 8002, 8003, 8004, 8005)
UPDATE asterisk.users SET recording='out=Always|in=Always' WHERE extension >= 9001 AND extension <= 9145

   The above queries updates the recording setting for extensions in database. The effect for extension 8001 may be seen at http://Your-Asterisk-Freepbx-Server-Domain-Name/admin/config.php?type=setup&display=extensions&extdisplay=8001

2. Open each extension page and press the submit button. Finally click “Apply Configuration Changes” so that the changes may be propagated in running asterisk server

At the datacenter the “IP KVM Virtual USB drive” wire was black and so were the power cables going into each of the servers.

We replaced the black wire with a red wire.

Now when we call remote hands to put the red wire labeled “IP KVM Virtual USB drive” to the USB port on one of the servers it would be so much easier,

On this server the operating system is installed on the 8GB compact flash card. So that the 10 hard drives of 1 TB each can be dedicated just to store the data in Raid1 and LVM on top of it.

Some of the things we are doing to install the OS on the flash card:
1. /var will be on the hard disk.
2. noatime for each of the partitions mounted on the flash card.

This article helped us quite a lot in optimizing our OS installation for the flash card:

Here is the picture showing the cable flow in and out of the “Mc Mans tel” box

From this black box made by McManstel there are two yellow eth5 cables that come out and go inside the Cisco Catalyst 2950 switch.

Cisco 2950 is a 24 port switch and on the far left of the following picture you will see the two output wires green and grey coming out of the cisco switch and going to my linux servers.

The probpem is:

1. Each port on the cisco 2950 switch is restricted to 512 Kbps of upload. I can get 12 Mbps of upload speed but for that I will need to run 24 parallel connections. I am hoping to get that 12Mbps of upload with just one port of the cisco 2950 switch instead of having to use all the 24 ports.

Wondering what is the solution ?
