Overview
The Grandstream GCC-UC-Extra-100-EXT PBX Add-On is a one-time licence that adds 100 users or extensions to the phone system built into a GCC6020 or GCC6021, for an organisation that keeps growing. A GCC convergence device combines a VPN router, firewall, switch and IP PBX (office phone system) in one box, and PBX upgrades add extensions or simultaneous calls to the built-in phone system as the office grows, instead of adding a separate PBX.
Is it right for you?
- Suits a GCC602x device whose built-in PBX has reached its current extension limit.
- Several add-ons can be ordered together, so you can add extensions in steps of 100 up to Grandstream’s capacity guideline.
- Not for GCC601x devices, which use the GCC-UC-Extra-50-EXT add-on.
- It does not add concurrent calls. If more people will be on calls at once, a GCC call add-on is the one for that.
Key features
- 100 additional users or extensions on the built-in PBX.
- Concurrent call capacity is not changed by this add-on.
- Multiple orders are allowed on the same device.
- One-time fee for the life of the product, with no renewal.
What else you need
- A Grandstream GCC6020 or GCC6021 convergence device.
- Only if peak simultaneous calls will also rise: a GCC call add-on as well.
Installation
There is nothing to fit. The licence is digital and is applied to the specific GCC device by your installer or IT team, who then adds the new extensions or phones.
Before you buy
- This is a digital licence with no physical item. It is applied to the specific GCC device, and activation is confirmed on your quotation.
- Applies to the GCC602x series only: GCC6020 and GCC6021.
- For GCC602x devices, Grandstream’s capacity guideline allows up to 500 users with 120 concurrent calls, 750 users with 90 calls, or 1,000 users with 60 calls.
