Here is the respone from the customer (Maximizer user)
""Myron, the Model of the system is ShoreTel 230. The argument I'm getting from both sides is that the two are not compatible with the version of TAPI each has. Neither one will switch to the other's version. You are right. It is software.
I have other issues with Maximizer in that they are slow with upgrades and they charge too darn much for training from which there is little value. I think they are milking the shrinking customer base they have. The Techie in Milwaukee is loosing business right and left and probably will drop doing what he is doing as the result. ""
Interesting. Everyone is in the same boat.
