Phone handset for EL52303
I have an EL52303 phone system and I need to purchase an extra handset. The EL50005 handset looks identical to the handsets included in my phone system, but apparently the correct handset I need to buy is the EL5003, according to the info here:
However l can't find the EL50003 available except from second-hand and third-party sellers. Is it possible that the EL50005 would work with my system?
