Overview - Grandstream Networks UCM6100 Series Configuring

OVERVIEW

This document describes basic configuration to interconnect UCM6100 series and GXW410X. In this
example, we will be using a GXW4104. The following methodology can be used for the GXW4108 as well.
This is typically applied to the scenario where users would like to add a GXW410X not only as a remote
extension but also as an external PSTN trunk.
There are two ways to set up the UCM6100 series IP PBX with the GXW410X.
•
Method 1: Register the GXW410X to the UCM6100 directly.
•
Method 2: Configure GXW410X as a SIP peer trunk.
Warning:
•
When the UCM6100 series is interconnected with other GXW410X, it is NOT recommended to
turn on "Allow Guest Calls" under the UCM6100 web GUI->PBX->SIP Settings->General.
Turning on this option will allow unauthenticated calls coming through the UCM6100 series.
Please be aware of the security concerns when using this option.
•
When using the IVR in UCM6100 series, please be aware that if "Dial Trunk" option is turned on in
IVR settings, the call into the IVR will be able to dial outbound call using UCM6100's trunk. The
IVR's permission level will be used when making outbound calls in this case. Please select proper
permission level for the IVR to control the outbound calls allowed via "Dial Trunk".
