Frequently Asked Questions
Log into the Grandstream Cloud Connectivity portal, go to the license management section, and enter the license key provided at purchase. The system should increase the concurrent call capacity immediately. If the license does not appear, verify that you registered the correct GCC serial number and MAC address when ordering.
First, double-check that the license was applied to the exact system using its serial number and MAC address. Then, refresh the license via the portal or restart the system. Confirm that the license shows as active in your account. If the issue persists, a Toronto-based VoIP support provider can usually resolve this remotely.
No, this add-on is specifically for the Grandstream Cloud Connectivity (GCC) system or compatible UCM models that support the extra 4-call upgrade. Check the product documentation or contact a reseller to confirm compatibility before purchasing.
Once all 24 call paths are in use, new call attempts will receive a busy signal or be rejected. If you consistently hit that limit, consider a higher-capacity solution or a further system expansion.
No, this is a software license upgrade. There is no physical installation—you simply apply the license key through the system's management interface.
License upgrades are typically tied to the original GCC serial number and MAC address. Check with Grandstream or your reseller about transfer policies; generally, they are non-transferable.
Ensure you are typing the key exactly as provided, with no extra spaces or characters. Verify that the license key matches the GCC serial number of your system. If the error continues, contact the point of purchase for validation.
Log into the system's web interface or GCC portal and look for a call capacity or system usage report. This will show the number of active calls and how many concurrent paths are in use.
Yes, it works with any SIP trunk provider as long as the trunk configuration is compatible with Grandstream systems. The upgrade only increases local capacity; carrier compatibility depends on trunk settings and provisioning.
The description states that this upgrade brings total capacity to 24, but it does not specify if multiple licenses stack. Consult Grandstream documentation or support to determine the maximum call capacity for your specific system before ordering multiple copies.

About This Product
This add-on license is designed for businesses already using a Grandstream Cloud Connectivity (GCC) system who need to support more simultaneous conversations. It is a pure software upgrade that adds four additional concurrent call paths, raising the total capacity to 24 calls. This fits well in a growing small-to-medium office, such as a GTA-based company that is starting to handle more inbound or outbound traffic but does not require a full-scale call center. The upgrade is straightforward to apply through the existing management portal, with no hardware changes needed.
The non-cancellable and non-returnable nature of this license means buyers must carefully verify compatibility before purchase: you will need the exact GCC serial number and MAC address of the system you plan to upgrade. It pairs naturally with Grandstream UCM series IP PBXs or the GCC cloud service, replacing the need for a secondary system if you simply need a few more lines. However, if your office routinely exceeds 24 concurrent calls, this upgrade may be underpowered—consider a higher-capacity platform or a multi-system setup.
For Canadian businesses, this license works seamlessly with SIP trunks from carriers such as Rogers, Bell, or Telus, provided the trunk is configured correctly. It is a low-risk way to extend capacity without replacing hardware, but it is overkill for a shop that rarely uses more than a handful of lines. Always confirm that your current system supports the upgrade before purchasing to avoid compatibility issues.
