3.3.7 Configuration & Update Service (DLS)
The Deployment Service (DLS) is a HiPath Management application for administering work-
points in both HiPath and non-HiPath networks. Amongst the most important features are: se-
curity (e.g. PSS generation and distribution within an SRTP security domain), mobility for opti-
Point and OpenStage SIP phones, software deployment, plug&play support, as well as error
and activity logging.
DLS address, i.e. the IP address or hostname of the DLS server, and DLS port, i.e. the port
on which the DLS server is listening, are required to enable proper communication between
phone and DLS. The Contact gap parameter controls a security function. It specifies a mini-
mum time interval that must elapse between HTTP requests; any requests coming within that
time will be ignored. The purpose is to prevent DoS (Denial of Service) attacks on the phone.
The Security mode determines whether the communication between the phone and the DLS
is secure. A secure connection is established by exchanging credentials between the DLS and
the phone for mutual authentication. After this, the communication is encrypted, and a different
port is used.
Data required
• DLS address: IP address or hostname of the server on which the Deployment Service is
running.
• DLS port: Port on which the DLS Deployment Service is listening.
Default: 18443.
• Contact gap: Minimum time interval in seconds that must elapse between HTTP requests,
in order to prevent DoS attacks.
Default: 300.
• Security mode / Security status: Determines whether the communication between the
phone and the DLS is secure.
Value range: „Default mode", „Secure mode".
Default: „Default".
