User Reviews

Users overall praise MaX UC for business-use calling from anywhere, with features like viewing extensions, four-digit dialing, and the ability to call from the app as if from the office; it's often labeled as essential for businesses. However, reliability issues dominate: frequent crashes after iOS updates; difficulty answering incoming calls (often goes to voicemail or fails to connect); audio problems such as the speaker turning off or the mic remaining active after calls; and unreliable chat/messaging with missed or duplicated messages. Focus mode ignore is also noted. Overall strong value when functioning, but critical stability fixes are needed.

Pros

Allows taking and managing work calls from anywhere, with office-like features (seeing extensions and 4-digit dialing).
Described as the best phone call reviving app on the market.
Love the ability to answer calls from anywhere.
Recommended for all businesses.
Some users report reliable calling on newer iPhone models (e.g., iPhone 15) with up-to-date iOS.

Cons

Frequent crashes and instability after iOS updates (crashes on launch or during use).
Inability to reliably answer or receive incoming calls (often goes to voicemail or fails to connect).
Audio issues during calls, such as the speaker turning off unexpectedly or the microphone staying active after calls.
Unreliable messaging/chat with duplicate notifications, missed messages, and poor synchronization.
The app ignores Focus mode, causing unwanted ringing.

It is a very nice solution in-shorts distances and solves problems wherever you need a calling/contacting platform to connect with people

I work for a company that uses MaxUC for our business phone service and for the most part if works quite well. Being that we provide the product internally I can easily get assistance, however, ever since iOS 26 this app has been absolutely awful. While audio remains fine, if music is playing and I dial out, the music will start again while making call; this doesn’t occur on inbound calls. In addition, lately speaker shuts off automatically for no apparent reason. If the dialogue box is open and I keep it up the speaker will stay on. If speaker is launched from a locked phone when call comes in there are no issues unless phone needs to be unlocked. Another issue is related to the speaker issue that then causes the mic recording light to stay on, or the mic in the Dynamic Island. If these particular issues could be resolved app could go back to 5 stars but at current it is quite atrocious.
