What are the benefits of Grandstream UCM6300A IP PBXs?

There are many video conferencing services on the market that businesses already subscribe to, like Zoom. The UCM6300A Series offers professional telephony control to businesses who wish to go with a separate video conferencing service, so you’re not paying for features you don’t need. Or maybe your business just doesn’t use video conferencing, which is still a common situation.

Think of UCM6300A as part of a modular solution that allows you to build the communications system your business actually needs without paying for stuff you don’t need.
