I have a new customer moving into an office that has a Strata 16e system that has been there forever. No one has used this building for a few years so I am not even sure if the system still works. When I asked him about phones, he brought in two new Toshiba DP5130 phones and said this is what the home office tech guy gave him. We have a lot of Toshiba systems still in use but have not installed any for several years. I am not familiar with this phone model, let alone what systems it will work with. Can anyone tell me if this phone will even work with the 16e system? Any responses please email to: [email protected]. Thanks for any and all input.
