SIP Proxy configuration
The configuration of the SIP Proxy is a carefully designed and implemented logic, do not modify it unless you fully understand how it works.
 
The SIP Proxy main configuration flow diagram is available in the documentation of the openser-xs-config Debian package installed on the SIP Proxy machine sip:/usr/share/doc/openser-xs-config/opensercfg.pdf.gz
The SIP Proxy behaviour is driven by /etc/openser/openser.cfg, which is automatically generated from the following files:
  1. Main configuration file /etc/openser/config/openser.m4
  2. Main settings file /etc/openser/config/settings.m4
  3. Site specific configuration files /etc/openser/config/siteconfig/*
The main configuration file will be overwritten after a platform upgrade. Do not change this file without permission from AG Projects. To perform changes of the Proxy configuration site specific files go to directory to

sip:/etc/openser/config/siteconfig/

You may safely modify settings.m4 and other files in site config directory. Safely means merely that the changes will be preserved during upgrades. Do not edit opensercfg.m4, which is overwritten during software upgrades by AG Projects. To rebuild the configuration and restart the proxy with the new configuration run:

/etc/init.d/openser reconfigure
 
This will generate /etc/openser/openser.cfg and check it for any syntax errors.

To restart the proxy with the new configuration:
 
/etc/init.d/openser restart
 
Check the proxy logs using tail -f /var/log/syslog to see if the software restarted correctly
