ESI 45 SIP Cloud Business Phone

Having the ESI Cloud PBX solution lets you choose from among multiple attractive and highly convenient ESI phones. Each is a great addition to virtually any office decor, but it’s far more than just a “pretty face.” The ESI 45 SIP Business Phone is ideal for most active ESI Cloud PBX users. Its large display and 16 programmable feature keys help you achieve maximum productivity. The ESI 45 SIP has a sealed membrane below the keys to make it virtually spill-proof; and the sturdy multi-position angled base lets it fit on any desk or counter space so you can easily see the status of the display and keys. The ESI 45 SIP also can be wall-mounted. It includes an adjustable backlit display and has a high-definition full-duplex speakerphone.
