Configuring UCM6XXX with GXW410X
OVERVIEW
This document describes basic configuration to interconnect UCM6XXX series and GXW410X. In this
document, we are using GXW4104 as an example. 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 UCM6XXX series IP PBX with the GXW410X.
• Method 1: Configure GXW410X as a SIP Peer Trunk.
• Method 2: Register GXW410X on the UCM6XXX directly as an extension.
Note: UCM6XXX series include UCM6100 series (UCM6102, UCM6104, UCM6108 and UCM6116),
UCM6200 series (UCM6202, UCM6204 and UCM6208) and UCM6510.
Warning:
1. When the UCM6XXX series is interconnected with other GXW410X, it is NOT recommended to
turn on "Allow Guest Calls" under the UCM6XXX web GUI->PBX->SIP Settings->General. Turning
on this option will allow unauthenticated calls coming through the UCM6XXX series. Please be
aware of the security concerns when using this option.
2. When using the IVR in UCM6XXX 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 UCM6XXX'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".
