If you're looking to Download IPMobility on your Chromebook laptop Then read the following guideline.
IPMobility allows the mobile device to act as an extension of the office desk phone by providing a single-number-reach to the user. With single number reach the mobile device can be used interchangeably with the office phone in order to make and receive calls. Presence status such as ‘busy,’ ‘out of office,’ can also be set, allowing the user to designate handling of incoming calls. The user can also easily access key voice messaging functionality and manage administration of the voice mail box without dialing into the voice mail system and navigating key presses or voice commands. The application does not interfere with the ability to make a phone call or access the voice mail of the mobile device itself. Requires Toshiba IPedge or Strata CIX with Strata Messaging.
