Description
If you are weighing options, the Grandstream UCM6304 is an IP PBX appliance we often suggest. It brings room for 2000 users and 4 FXS ports, which matters more than it sounds.
How we can help
Choosing between on-site and hosted is a big decision. We help you weigh both, and if the UCM6304 wins, we configure it before it ships.
Who we recommend it for
- Multi-office groups
- Businesses with existing analog gear
- Regulated industries
Features worth knowing
- Gigabit pass-through, which saves a second network drop at each desk
- Runs on PoE, so one cable to the desk is enough
- Handles up to 300 calls at once, so busy hours are covered
- Sized for teams of up to 2000 users
- 4 FXS port(s), so existing analog phones and fax keep working
- 4 FXO port(s) if you need to keep some copper lines
- Built-in security features to protect calls and settings
