SER Multi-domain support

Satish patel

I am working on SER since last 3 month and i have good knowledge of SER functionality finaly i have decide to implement Multi-domain because I have many VOIP customer and i have configure domain name base on users like john@example.com can call to eric@example.com , also there is one more domain satish@linuxbug.org and priya@linuxbug.org can call to each other not inter-domain.

Now i am going in detail configuration Now configure Mysql Server on your SER server and run database script to create mysql tables

This is my working configuration


cat /usr/local/etc/ser/ser.cfg
