Hey guys, i have a sort of special needs customer that is looking for a wireless handset solution for their executives. Here's the issue, they don't like the smaller form factors that have come out recently because some of them are older folks, and the smaller keys are hard on them. They currently use the Avaya 3910s, which they like, but they are having issues with them and cannot get replacements, etc. as they are discontinued. The other issue is line appearances. The 3910 allows them to have 4 programmable lines, and this is a must for any replacements. They each have a personal line, a normal business line connected to an OPX, a security line connected to a door access system, and then a line for their assistants. Have you guys tried the D160? How does it compare? Do you know of a 3rd party phone that would work with the IPO?
