GOautodial Open Source Omni-channel Contact Center Suite

I have followed all the instruction from https://goautodial.org/projects/goautodialce/wiki/Version_4_How_To_Install_Goautodial_From_Scratch_using_CentOS_7X.

In the step of ' Create "goadmin" Admin user account '

use goautodial;
INSERT INTO users(userid,name,fullname,avatar,role,status,user_group,phone) VALUES('1416','goadmin','Admin User','','9','1','ADMIN','7798306534');

running that code gave me an Error which says no table found.

And I found my database structures is different than Instruction does.
Did I miss some steps? or Database has updated?

Also, When I run "systemctl enable ngcp-rtpengine",
it gave me an Error "No such file or directory".

I appreciate your help, and sorry for my bad English.
