Telo (black) has only one PHONE port that can only feed ONE conversation. The WALL jack is not used to connect telephones and the PHONE port is wired for a single pair. If you have more than one number, you can answer either number from the connected phone and you can force caller ID for any of your numbers. If you want more than one conversation at a time, you must have a Telo proprietary handset. You can make said handset a personal device and assign a number to only ring on that handset.
Hub (white) has access as above - but if you have Premier and use a scout (the pair is called the ooma core system) then you can feed line 1 from the hub and line 2 from the scout. Many folks keep them stacked on their desk to save room and have the PHONE outputs drive a 2-line phone system as you propose.
Two more things - (1) welcome to ooma and to the forum! and (2) you might want to call customer support at 888 711-6662 and have them change your username to something besides your phone number. I for one don't like having my number accessable to all the spammers, scammers, and bots that search the Internet for phone numbers.

Friends don't remember what Landline Integration was or why we did it.
