Issabel – how to change recording location
In Issabel, you can change the recordings location by modifying the “monitor” settings in the asterisk configuration files.
Here are the steps to change the recordings location:
- Log in to your Issabel server using SSH.
- Navigate to the Asterisk configuration directory by running the command:
cd /etc/asterisk/. - Edit the
logger.conffile by running the command:nano logger.conf. - Scroll down until you find the section that starts with
[general]. - Look for the line that starts with
dir=under the[general]section. This is where you can set the default directory for your recordings. By default, it should be set to/var/spool/asterisk/monitor. - Change the directory to your desired location for the recordings. For example, you could set it to
/home/issabel/recordings. - Save the changes to the
logger.conffile and exit the text editor. - Restart the Asterisk service by running the command:
systemctl restart asterisk.
After making these changes, all future recordings will be stored in the new directory that you specified.
Disable weak algorithms at the server side
1. First, we log into the server as a root user.
2. Then, we open the file sshd_config located in /etc/ssh and add the following directives.
Ciphers aes256-gcm@openssh.com,aes128-gcm@openssh.com,aes256-ctr,aes128-ctr
MACs hmac-sha2-512-etm@openssh.com,hmac-sha2-256-etm@openssh.com,umac-128-etm@openssh.com,hmac-sha2-512,hmac-sha2-256,hmac-ripemd160,hmac-sha1
KexAlgorithms diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1
Asterisk Call parking : adding more time
Issabel uses the default call parking module from issabel. Sometimes the module default time is set to 45 seconds. To change the call park time in issabel you need to edit the following file.
/etc/asterisk/features_general_additional.conf
and add the following line after pickupexten=*8.
parkingtime =>300 (this equates to 5 Minutes)
save and reload your asterisk application.
Search for large files
In Linux sometimes you need to locate the largest file in your system. To do so, you need to select the mount location when searching.

Base repository of CentOS has no php7 packages.
You can use remi repo to install php7 on your CentOS 7.
Why Remi?
- PHP package installed from remi repo will work as drop-in replacement for your current php5 binaries.
- Remi repo is managed by one of PHP internals
- Why not?
To install the Remi repository, we need to enable the EPEL repository first.
sudo yum install epel-release yum-utils
