  1. Installing the GS Wave Application requires many permissions which some individuals might find alarming.

    Here is an explanation of permissions. Permissions are required to make a voice call (Contacts, Microphone, Bluetooth, Phone), video calls (Camera) to make sure you aren’t using your cell phone on another call (Device ID & Call Information) and it can be limited to use Wi-fi instead of your phone’s data plan (Wi-Fi connection information). It also requires access to you can write settings to the phone (Photo/Media/Files) and can display a unified call log for both GS Wave and your phone in the application (Call Logs).

    Grandstream is headquartered in Boston, MA, USA and is governed by US and International laws.

  1. Within 20 seconds the newly added extension, in this case 1000, will have a green dot next to it to indicate it is registered with the UCM and can make and receive calls at the extension using the GS Wave application. If the dot does not turn green please contact your phone administrator for guidance.
  1. Next click on the Keypad at the bottom and dial *97 (star97) to check your voicemail or dial extension inside your organization to test if it is working correctly.

You can use this application to make an receive calls using the office PBX.

NOTE: When you make calls using this application the person you are calling will see it is from your company’s number and not your cell phone number. This will make for a higher first-call completion rate since most businesses know the company number on their caller ID and not your personal cell phone number and they will take the call instead of letting it go to voicemail.

The user manual for the GS Wave application is available here.
