### 2/5 — Clunky, basic, sad

*2026-08-16, version 1.33.14*

Update. 1 month short of a year they respond.  The rating shows the app. Needs polish. Step up to the level Grandstream is trying to jug to represent. 

App does stuff. Can’t logout of an old account.  Nothing amazing considering its part of their premium platform offering and they are big in the VoIP business.

### 4/5 — Was Totally Unusable on iOS - NOW FIXED

*2026-08-16, version 1.33.14*

EDIT- 

GRANDSTREAM HAVE NOW FIXED MY EARLIER ISSUES. THE APP WORKS GREAT. 

“Calls don’t come through unless the app is open and on the screen. I just get a missed call notification. The rest is fine but this lack of basic functionality makes the app unusable.”

### 5/5 — New update is working ok now on iOS

*2026-08-16, version 1.33.14*

After resolving a network configuration issue on our UCM6304, Wave on iOS is now working very well. Registration is fast, call quality is excellent, and both incoming and outgoing calls are reliable.

I especially appreciate the detailed diagnostic logs available in the mobile app—they were extremely useful in identifying that the issue was related to the SIP/TLS network path rather than the extension itself.

One improvement I would really like to see is clearer troubleshooting information inside the app when HTTPS login succeeds but SIP registration fails. A message such as “SIP/TLS server unreachable on port xxxx” would save administrators a lot of troubleshooting time.

Overall, Wave is a very capable companion to the UCM platform, and after getting the network configuration right, the experience has been excellent.

### 1/5 — Problematic

*2026-06-10, version 1.33.9*

Ive been using this app for receiving calls from my work/business number to my phone for about 6 months now.  First issue is that it must be open to receive calls.  There is no option to automatically receive call notifications without opening th app ans having it run in the background.  

The second issue is that the call history is sporadic, where some calls that should be patched through are, and some are not.  

The third issue is that there is no text functionality and a lot of business is conducted by text which forces me to use my regular cell number and defeats the purpose of having one business number for both office and cellphone.

### 5/5 — Powerful and easy to use

*2026-04-14, version 1.33.9*

This app is powerful and easy to use, the meeting setup is easy, I can use it to audio/video call, host meeting with internal and external attendees, message chat, OA process, AI helper, etc. And the desktop version even supports more features. I love this app so much that it supports my daily work very well!

### 2/5 — Not Functioning

*2026-04-09, version 1.33.9*

I have an iPhone with latest update. The app keeps closing and can’t be used. I’d there a way to fix that?

### 1/5 — Login broken

*2026-03-18, version 1.33.7*

This app used to be fantastic but unfortunately recent updates seem to have broken login and it is now unusable

### 1/5 — Mute!!

*2026-01-23, version 1.31.7*

Need a setting on iPhone app to silence/mute calls for after hours. Android version seems to have a way to do that.

### 1/5 — Unusable after updating

*2025-12-29, version 1.31.5*

The latest update has completely broken this app. It used to work well for me but now won’t even open DO NOT UPDATE

### 1/5 — Does not work on iPhone

*2025-12-26, version 1.29.12*

Our premise has ucm setup to allow voip calling over the lan network. The wave app on android phones work perfectly fine, receiving calls and notifications just like for instance WhatsApp. However on iOS devices it seems I cannot receive calls when I am not on the app. This is a huge problem as it should be running in background so that I can receive calls even when my phone is locked or is on another app. Please fix this
