Hi all,
I hav tried to understand SIP...im a totally new to sip, still a student learning.
How do I enable my Voice Mail in my ser.cfg....or where can i learn to add voice mail? I had vry little understanding with my ser.cfg file due to the server was created by previous project student...
here's ser.cfg
