Chances are you already own an office phone. They keep us in constant contact with our most valuable assets, our clients! Finding the right phone with the right balance of features and quality can be impossible at times, however had exactly what I was looking for. The Avaya 9640IP is easy to use and is exactly what I need without breaking the bank. Letís not forget about the warranty that is offered and the tech service is superb. The Customer care center was very knowledgeable about their product and what would work best for my needs. I would highly recommend for any of your phone needs--home or office!!–í


I specialize in installing phone systems, and this is one of the best phones for people that have high phone usage. Iíve never had any problems with programming or defects. The Avaya phones have clearly-labeled, fixed feature keys that people love, and I like not having to re-program everything when people want to customize their phones. The screen and set-up of this phone are very stylish too, if that is important to you. When I pull this phone out, itís an easy choice for department managers and IT professionals.–í
