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‼️
