I was hoping that the 5020 would work with the 5000 HX. I did try to do an install but it wasn't recognized using Class D license. I do see that there are other classes of IP phones that will work with the 5000 but I don't have any class a,b,or c License. I do have class D and have 15 Mitel 5330 phones installed. I have one license left and that is what I was trying to use. I guess I will get the correct module for a 5330 phone and use the 5310 on that unit.
Thanks for your reply.
