Giving root access is enough to do any thing on the system.

You can add one account to the system and provide him / her priv. using sudo.

Please see below link on how to use sudo:

root account is not restricted and it is not possible to restrict it. So you just gave out all your data and now got thinking ...

You need to turn the problem around and decide what operations & privileges the PBX server should be allowed on the CRM server, then set up new userid(s) with appropriate sudo privilege escalation.

Possibly something like "useradd" with root permissions plus "su - dbuser create_new_db_user_script" if your PBX system was the master identity server.

Though it might be even better to have the CRM server as the master and grant ssh access to the PBX (High security to Low security system)
