Looking for admin manual --> iPECS-300 Version : MFIM/AU96M-F.1Dq SEP/16

Hey All,

We have a VOIP network which needs to be configured and maintained.
Looking for a manual for the above (Not sure about the naming). Any idea where to get it from?

How to add a new user?
How to create new groups? Assign numbers to groups?
etc.
