According to the data sheet, the REN "Ringer Equivalence Number" of that device is 3. Powered phones use less than 1 REN, and all phones are supposed to have their REN number written on them somewhere. So it depends on your phones. ------------------------------------------------------------

Most likely, no problem if they aren't mechanical ringers. Each phone
should have a REN (ringer equivalent number) and the SPA should document
how many RENs it can drive.
But 4 should be no problem.
