3.3.8 Configuration & Update Service (DLS)
The Deployment Service (DLS) is an OpenScape Management application for
administering workpoints in communication networks. Amongst the most
important features are: security (e.g. PSS generation and distribution within an
SRTP security domain), mobility for OpenScape SIP phones, software
deployment, plug&play support, as well as error and activity logging.
DLS address, i.e. the IP address or host name of the DLS server, and Default
mode 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 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 Mode (labeled Mode in the local phone´s Admin menu) determines the
security level for the communication between the phone and the DLS. Mutual
authentication establishes a higher security level of the connection by mutually
exchanging credentials between the DLS and the phone. After this, the commu-
nication is encrypted, and a different port is used, thus ensuring that the phone is
unambiguously connected to the correct DLS server.
INFO: It is possible to operate the DLS server behind a firewall or
NAT (Network Address Translation), which prevents the DLS from
sending Contact-Me 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 periodically polls the DCMP (DLS Contact-
Me Proxy), which is placed outside of the phone’s network, for
