Review: A phenomenal PBX😁 - This UCM6304A replaced a Panasonic analog hybrid PBX that was about 15 years old. The UCM6304A then connects to a Tapo 10 port POE switch providing power and data to 8 Grandstream GXP2140 IP desk sets. I was only able to add the 8 phones to the PBX. After that, it simply too complicated for my pay grade😂 I ended up paying IP Phone Warehouse. Scott, a tech support wizard did a superb job of completing the setup. I can’t thank him enough. The UCM6304A has features that most people would never even think of. It is phenomenal, and at a great price‼️ Review: EXCELENTE - excelente ## Features - Audio Only - 1000 Users, 4 FXO, 4 FXS Based on Asterisk* version 16 open-source telephony operating system - Zero configuration provisioning of Grandstream SIP endpoints - Built-in Instant Messaging (IM), Audio Conferencing & Web Meetings platform that supports access from computers, mobile devices, and SIP endpoints - Free Wave App allows easy voice & Instant Messaging (IM) communications using desktops, Web, and Android/ iOS devices - API available for third-party integrations, including CRM and PMS platforms - Advanced security protection with secure boot, unique certificate and random default password to protect calls and accounts - Three Gigabit auto-sensing RJ45 network ports with integrated PoE+ and support NAT router - Automated NAT firewall traversal service facilitates secure remote connections - Compatible with GDMS for cloud setup, management, and monitoring ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09MJ66WKR | | Answering System Type | Digital | | Best Sellers Rank | #158,240 in Office Products ( See Top 100 in Office Products ) #8 in PBX Phones & Systems #15 in Big Button & Amplified Telephones | | Brand | Grandstream | | Color | Black or Gray | | Compatible Devices | Grandstream SIP endpoints, desktops, mobile devices, other SIP endpoints, VoIP services, answering machines, fax machines | | Conference Call Capability | 4 way | | Customer Reviews | 4.8 out of 5 stars 16 Reviews | | Dialer Type | Single Keypad | | Enclosure Material | Plastic | | Global Trade Identification Number | 06947273703570 | | Is there Caller ID | Yes | | Item Dimensions | 9.84 x 11.81 x 3.15 inches | | Item Weight | 0.78 Kilograms | | Manufacturer | Grandstream | | Material | Plastic | | Mfr Part Number | UCM6304A | | Model Number | UCM6304A | | Multiline Operation | Multi-Line Operation | | Number of Batteries | 12V batteries required. | | Power Source | Corded Electric | | Recording Capacity | 22 Minutes | | Telephone Type | Corded | | Warranty Description | 1 Year Manufacturer | ## Product Details - **Answering System Type:** Digital - **Brand:** Grandstream - **Color:** Black or Gray - **Dialer Type:** Single Keypad - **Item Weight:** 0.78 Kilograms - **Item dimensions L x W x H:** 9.84 x 11.81 x 3.15 inches - **Material:** Plastic - **Number of Batteries:** 12V batteries required. - **Power Source:** Corded Electric - **Telephone Type:** Corded ## Images ![UCM6304A Audio IP PBX | 4 FXO Ports, 4 FXS Ports | Desktop/Wall-Mount - Image 1](https://m.media-amazon.com/images/I/51AJxPOpoEL.jpg) ![UCM6304A Audio IP PBX | 4 FXO Ports, 4 FXS Ports | Desktop/Wall-Mount - Image 2](https://m.media-amazon.com/images/I/51KSWSgBTPL.jpg) ![UCM6304A Audio IP PBX | 4 FXO Ports, 4 FXS Ports | Desktop/Wall-Mount - Image 3](https://m.media-amazon.com/images/I/416TtiWapaL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A phenomenal PBX😁 *by T***8 on April 20, 2026* This UCM6304A replaced a Panasonic analog hybrid PBX that was about 15 years old.
