Overview
The Grandstream GCC-UC-Extra-4-Call PBX Add-On is a one-time licence that lets four more people be on calls at the same time on the phone system built into a GCC convergence device. 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 GCC601x or GCC602x device where callers hit the simultaneous call limit at busy times.
- Several add-ons can be ordered together, so you can add calls in steps of 4 within Grandstream’s capacity guideline for your series.
- It does not add users or extensions. For more people, the GCC-UC-Extra-50-EXT add-on is the one for that.
Key features
- 4 additional concurrent calls on the built-in PBX.
- User or extension count 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 GCC series convergence device: GCC6010, GCC6010W or GCC6011 (GCC601x), or GCC6020 or GCC6021 (GCC602x).
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 GCC series PBXs on both GCC601x and GCC602x devices.
- For GCC601x(W) devices, Grandstream’s capacity guideline allows up to 100 users with 24 concurrent calls, 150 users with 20 calls, or 200 users with 12 calls.
