This document describes one reason why Sony video endpoints such as
PCS-TL30 and PCS-TL50 fail to register with Cisco Unified CallManager and
provides a solution in a Cisco Unified CallManager environment.
Cisco recommends that you have knowledge of these topics:
The information in this document is based on Cisco CallManager version
4.1 and later.
The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.

The Cisco CallManager solution can be integrated with the Sony PCS-TL30
and PCS-TL50 desktop units for group video conferencing. The Sony PCS-TL30 and
PCS-TL50 are a network-ready video communication system that allows you to
instantly communicate with your business counterparts over IP networks.
Key features of the solution include these features:
The PCS-TL30 and PCS-TL50 terminals that operate with Cisco
CallManager 4.1 enable users to dial the phone number of the video conference
call without needing to input IP addresses.
Users can easily connect to multiple parties within the same IP
telephony network, even if some are not on a video conferencing
The PCS-TL30 and PCS-TL50 allow users in the Skinny Client Control
Protocol (SCCP) network to directly dial conference call attendees who might be
on different devices (for example, mobile phones) and/or different networks
(for example, DSL, mobile cellular).
Sony PCS TL30 and PCS TL50 can communicate with Cisco Unified
CallManager using SCCP protocol (see Figure
Figure 1—Network Topology
Cisco Unified CallManager is configured to support Sony PCS-TL30 and
PCS-TL50 based on the
Cisco CallManager Setup Guide
published by Sony. These two
tasks have been completed:
The Sony PCS Plug-in was installed on the Cisco Unified CallManager
Sony video endpoints were added to the Cisco Unified
However, Sony PCS-TL50 and PCS-TL30 fail to register to Cisco Unified
CallManager. This error is identified in the application event log:
Error: DeviceTransientConnection - Transient connection attempt.
Connecting Port: 0

This problem is an installation issue. In order for Cisco Unified
CallManager to support Sony PCS-TL30 and PCS-TL50, you must install the Sony
PCS Plug-in on all Cisco Unified CallManagers in the cluster. When the problem
happens, the Sony PCS Plug-in is only installed on the Cisco Unified
After you install the Sony PCS Plug-in on all Cisco Unified
Subscribers, Sony PCS-TL30 and PCS-TL50 successfully register with the Cisco
