The ESI 250 Smartphone for the Desktop is an enterprise-grade smartphone for small and medium-size businesses. It looks like a regular office phone but has a 7-inch color touchscreen and third-party apps such as Evernote. The ESI 250 lets you send text messages and record calls, and it offers features such as reminders, automatic call distribution, and advanced conferencing. The phone uses VoIP running on ESI servers that support 5 to 300 phones. Slated for release in June, the ESI 250 will be available through resellers for $400 to $500.
