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‼️

Great PBX for DIY
Great value for a PBX but I have a few quirks that my last generation pbx didn't have.

Great for Collectors of old phones as well! (*With use of an ATA that supports Pulse Dialing.*)
Very easy to program and allows use of older touch tone phones as well. For rotary support one will need to get one of the ATA's that support rotary pulse dialing. I ordered the ATA-818 to work with this PBX allowing rotary phones within my collection to work within this phone system. Over all its has allow of features that would used be licensed features on products offered by major brands. This device is perfect for my needs. It also offers video/chat Skype like program called WAVE for devices that support it (Smart phones, tablets and PCs)
