Thanks in advanced. I am working with a Avaya G3siV11. I have mostly digital 6408d+ and analog 2500 & 8110M phones on our switch. The site is likes the features of the 6408d+ but not the price. Where can I find out what types of phone my switch and cards can handle? Also any suggestions on cheaper analog or digital phone with the same capabilites as the 6408d+? Will analog phones work with ac power work on most analog cards?
