Today’s competitive and fast past business environment means that employees are no longer bound to a desk - you need to be mobile and be able to work where your work takes you. NEC’s UNIVERGE ST500 softphones for Android smartphones allow you to make and receive calls from virtually anywhere, as if you were at your desk. While in the office connect to the Wi-Fi to handle your calls. While outside the office you can use your mobile data (3G / 4G) to handle you calls, and you can reduce incurring mobile call costs (See Notes below).

Deploying a ST softphone can save your company money by no longer having employees call-forward their desk phones to their mobile. Staff will also be able to make free internal calls and inexpensive local calls from the softphone rather than all calls being made directly from their mobile phone.

By only giving out your desk phone number (not your mobile number), you will always be contactable and you will only have a single call history and work voicemail to check. The ST500 simplifies your communications.
