CCS-UC-1: SIP Endpoint with Cisco
Unified Communications Manager
10.5
Introduction
This configuration guide describes the necessary procedure to configure the Crestron
Mercury™ device to register to the Cisco®Unified Communications Manager as a basic SIP
endpoint.
Audience
This document is intended for users attempting to configure and use the Crestron Mercury
devices as SIP endpoints registering to the Cisco Unified Communications Manager (Cisco
UCM).
Topology
The network topology for the Crestron Mercury endpoint to interop with the Cisco UCM is
shown below.

CCS-UC-1: SIP Endpoint with Cisco UCM 10.5 Configuration Guide – DOC. 7993A
The lab network consists of the following components:
•Cisco UCM cluster for voice features
•Cisco SIP phones
•Crestron Mercury devices as SIP endpoints
Software Requirements
•Cisco Unified Communication Manager v 10.5.2.13900-12
•Cisco Unity Connection v 10.5.2.13900-12
•Crestron Mercury device v 1.3353.00029
Hardware Requirements
•Cisco UCS-C240-M3S VMWare Host running ESXi 5.5
•Cisco 3845 as PSTN Gateway
•Cisco phone models: 8961 (SIP), 8945 (SIP)
•Crestron Mercury devices (2)
Product Description
The Crestron Mercury device is a complete solution for conference rooms. It acts as an
all-in-one touch screen, speakerphone and AirMedia®product for conference rooms
that integrate microphones and speakers into the user interface at the table.
Crestron Toolbox™ software is used to discover and control all Crestron devices on the
network.
The Crestron Mercury web interface is used to control the Crestron Mercury devices on
the network.
Summary
The Crestron Mercury devices were configured on the Cisco UCM as basic SIP endpoints
since they support only a single line/extension. The devices successfully registered to the
Cisco UCM with digest authentication.
The sections below describe supported and unsupported features on a Crestron Mercury
device.
Features Supported
•Registration with digest authentication
•Basic Calls with G729, G722, G711u, and G711a codecs
•Caller ID (limited to only calling number)
•DTMF support
•Early media support
•Retrieval of a parked call

•Transferee in a call transfer
•Conference participant
•Member of hunt group
•Voice mail access and interaction
Features Not Supported
•Caller ID presentation with name and number display
•Call hold and resume
•Call forwarding on the device (Forwarding can be configured on the PBX for the DN
assigned to the endpoint.)
•Call waiting
•Conference
•Initiating attended call transfer
•Initiating semi-attended call transfer
•Initiating blind call transfer
•Configuration of shared line on device
•Initiating call park
•Do Not Disturb (DND)
Known Issues and Limitations
•The Crestron Mercury device does not allow calls to be placed or accepted as long
as the SIP server is unreachable and the device is un-registered. This causes an
established active call to be dropped in a scenario where there is a PBX network
outage due to the device losing its registration status. This issue is tracked via
Crestron’s Bugzilla™ software Defect: 128016.
•Caller ID is not supported on the Crestron Mercury device. Currently, only the
calling party number is displayed as the caller ID. This issue is tracked via
Crestron’s Bugzilla software Defect: 119006.
•The active call timer on the Crestron Mercury device does not reflect the correct call
duration. The active call duration includes the time for which the unit was being
alerted also. This issue is tracked via Crestron’s Bugzilla software Defect: 124001.
•The first ringback heard on Crestron Mercury device is stuttered. It resembles a mix
of local and remote ringback. This issue is tracked via Crestron’s Bugzilla software
Defect: 122421.
•On the Crestron Mercury web user interface, there is currently no notification
provided to the user when certain mandatory configurations are missing. This issue
is tracked via Crestron’s Bugzilla software Defect: 125193.
•On the Crestron Mercury web user interface, a configuration of DHCP OFF on the
Network configuration page mandates configuration of both the adapters. The user
is unable to save changes unless both the adapters are configured and is notified of
an invalid IP against the default of 0.0.0.0 for an unused adapter. This issue is
tracked via Crestron’s Bugzilla software Defect: 126236.

•On the Crestron Mercury device, for certain called numbers that cannot be reached
or are invalid, the user only hears a reorder tone and does not have the option to
disconnect the call except by pressing the call button again. This issue is tracked
via Crestron’s Bugzilla software Defect: 122633.
Crestron Mercury Configuration
Setup
The LAN port of the Crestron Mercury device needs to be connected to one PoE+ port to
power it up and network for connectivity with the Cisco UCM. The PoE+ switch that is used
should have the LLDP functionality enabled for the device to power up and be completely
functional. By default, the “poeplus” configuration is set to Off on the device.
Configuring the device
To configure the Crestron Mercury device, follow this procedure:
1. Access the web GUI for the device by using an http session with the device’s IP
address. 10.80.10.100 was used in this example as the device IP. The initial page
that displays is shown below.

2. Click
Sign In
and log in to the device. For information on device administration,
refer to the CCS-UC-1 Supplemental Guide (Doc. 7844) at
www.crestron.com/manuals.
The Status screen that appears displays basic information on the device.
