Hello
My first post here. I work for a company that has an Avaya CM system. We are beginning to talk about upgrades to the PBX, and the engineer is telling us that 2 pair digitals are no longer going to be supported after the upgrade. Initially this is no problem as we are replacing most 74xx phones with 2410’s. However in some locations there is still cat3 and pulling new wire is not an option to move to IP phones. The reason I bring this up about IP is the 2410’s do not have enough button support to replace the 74xx phones, and the other option is alternative powered side cars which is not acceptable because of regulations requiring phones independent of power fail. Are we getting a run around from our off site engineer? If not what phones do we have as an option?
