4 W52P IP DECT Phone Configuration
The W52P IP DECT Phone can be configured with a configuration file using the Trivial File
Transfer Protocol (TFTP) or through its embedded web server. The following examples
describe how to set the parameters using a configuration file. This configuration
description assumes the W52P IP DECT Phone uses the Dynamic Host Configuration
Protocol (DHCP) to obtain an IP address, TFTP server, and other network settings. The
W52P IP DECT Phone should be configured to load the configuration file each time it
resets or re-synchronizes. For detailed information on automated provisioning, refer to the
Yealink W52P IP DECT Phone User Guide [1].
The capabilities of the W52P IP DECT Phone have been verified for use with BroadWorks
based on the settings described in the following table. For more information on the
meaning, purpose, and applicability of the individual configuration items refer to the
Yealink W52P IP DECT Phone User Guide [1].

4.1 System Level Configuration
This section describes system-wide configuration items that are generally required for
each W52P IP DECT Phone to work with BroadWorks. Subscriber-specific settings are
described in the next section.
Step Command Purpose
System Configuration Items y0000000000<xx>.cfg
Step 1 Set SIP Proxy/Domain.
account.SIPServerHost =
as.broadworks.net
account.SIPServerPort = 5060
Set the W52P IP DECT Phone SIP
server to the Fully Qualified Domain
Name (FQDN) for the BroadWorks
Application Server cluster.
The domain must match the domain
configured for the BroadWorks
subscriber’s line/port domain.
Step 2 Set Outbound Proxy.
account.UseOutboundProxy = 1
account.OutboundHost =
sbc.broadworks.net
account.OutboundPort = 5060
Set the Outbound Proxy to the
session border controller (SBC) if one
is deployed between the W52P IP
DECT Phone and BroadWorks.
If there are redundant SBCs, set it to
the FQDN for the SBC cluster.
Step 3
ADVANCED.default_t1 = 0.5
ADVANCED.default_t2 = 4
ADVANCED.default_t4 = 5
The SIP timers should be set to levels
short enough to support a timely
failover when there is no server
response.
