Edit the configuration files in /etc/asterisk as desired. Suggested changes for a SIP only system are:

• cd /etc/asterisk
• vi extensions.conf indications.conf manager.conf res_config_mysql.conf
• ip a
• vi sip.conf

extensions.conf

• Change "extensions_enswitch_16.conf" to "extensions_enswitch_13.conf" if using Asterisk 13.

indications.conf

• Set the country. This must match one of the entries in the file.

manager.conf

• Change the password for enswitch. The value doesn't matter, as enswitch_routed reads this file directly each time it starts.

res_config_mysql.conf

• Set database server if a different machine.
• Set database password.

sip.conf

• If Kamailio is running on the same machine, change bindport to 5070.
• In [enswitch-local], set the public IP address of Kamailio in the host line.
• In [enswitch-local], set the primary SIP domain (if known) or public IP address (if the domain is not known) in the fromdomain line.
• Replace the [127.0.0.1] header with the public IP address of Kamailio in square brackets.
• In [127.0.0.1] (as changed above), set the public IP address of Kamailio in the host line.
• In [127.0.0.1] (as changed above), set the primary SIP domain (if known) or public IP address (if the domain is not known) in the fromdomain line.
• Repeat the above steps for the [127.0.0.1:5060] section.
