Mobile Devices and Softphones

While both the mobile application and softphone application can be installed, OTS highly recommends using the mobile application over the softphone application. This is due to the ease of configuration and the ease of use as the mobile application. The mobile application provides a much more natural telephone experience.

Mobile App



Softphone App

When using the softphone application, you will need to purchase a headset for your laptop/desktop. The recommended headset is the Logitech USB Headset H390 with Noise Cancelling Mic available from CDW in BuyIt.

Desk Phone Installation FAQs

Telephones connect via wired ethernet and require power over ethernet (PoE). If you have a PC, you need to connect it through the phone (in series). If you wish to use a separate wall jack for the phone and PC, there is a fee for the port activation.

  • The phone is not powering on.
    • The ethernet cable is connected to the wrong port on the back of the phone.
      • Plug the cable into the correct port on the back of the phone.
    • The Phone is connected to a non-PoE network port.
      • Contact the Support Desk with the information about the outlet. The Support Desk will have Network Services migrate the port to PoE.
    • Plug the phone into an ethernet port (where you would plug in your PC or printer).
  • The phone is not prompting for a Device ID.
    • Power cycle the phone by disconnecting the ethernet cable, wait for 30 seconds, then reconnect the ethernet cable. If the issue persists, the phone needs to be factory defaulted. Please contact the Support Desk to have the vendor reset the phone.
  • The Device ID is not accepted.
    • The extension has not been migrated from trunk users profile to VoIP profile.
      • Contact the Support Desk, we will validate if this number has been migrated to VoIP.
  • The phone was registered, but when you lift the receiver, you get a busy signal.
    • The phone was assigned the wrong profile.
      • Contact the Support Desk to have the profile changed.

      • Contact the Support Desk to confirm the migration was completed.
