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
Default mode portDLS
port
, i.e. the port on which the DLS server is listening, are required to enable proper commu-
nication between phone and DLS.
The
Contact gap
parameter is not used.
Set
Revert to default security
to disable mutual authentication and return to DEFAULT mode.
SECURE mode related settings are reset and certificates are removed.
The
ModeSecurity 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 dif-
ferent port is used.
A
Security PIN
can be provided which is used for decrypting data provided by the DLS during
bootstrap. For further information, please refer to the DLS documentation.

It is possible to operate the DLS server behind a firewall or NAT (Network Address
Translation), which prevents the DLS from sending ContactMe messages directly to
the phone. Only outbound connections from the phone are allowed. To overcome
this restriction, a DLS Contact-Me proxy (DCMP) can be deployed. The phone peri-
odically polls the DCMP (DLS Contact-Me Proxy), which is placed outside of the
phone’s network, for pending contact requests from the DLS. If there are contact re-
quests, the phone will send a request to the DLS in order to obtain the update, just
as with a regular DLS connection.
The URI of the DCMP, as well as the polling interval, are configured by the DLS. For
this purpose, it is necessary that the phone establishes a first contact to the DLS,
e. g. by phone restart or local configuration change.
