Integrating Polycom® HDX® Systems with UNIFY® OpenScape®
Polycom, Inc. 35
2 Configure the following settings:
○ Enable SIP Enable
○ Transport Protocol This field determines the protocol the system uses for SIP signaling. The
SIP network infrastructure in which your Polycom HDX system is operating determines which
protocol is required. You can choose from the following options:
» Auto Enables an automatic negotiation of protocols in the following order: TLS, TCP, and
UDP. This is the recommended setting for most environments.
» TCP Provides reliable transport via TCP for SIP signaling.
○ User Name Enter the directory number of the OpenScape Voice. This field specifies the SIP
address or SIP name of the system — for example,
[e-mail]. If you leave this field blank, the system’s IP
address is used for authentication. In a UNIFY environment, this setting is the Subscriber
number provided by the OpenScape Voice administrator.
○ Domain User Name Digest Authentication User Name. This field specifies the name to use for
authentication when registering with a SIP Registrar Server — for example,
[e-mail]. If the SIP proxy requires authentication, this field and the password
cannot be blank.
○ Password Digest Authentication Password. This field specifies the password that
authenticates the system to the Registrar Server.
○ SIP Registrar Server OpenScape Voice IP or DNS-Name (preferred). This field specifies the
IP address or DNS name of the SIP Registrar Server. By default for TCP, the SIP signaling is
sent to port 5060 on the registrar server. By default for TLS, the SIP signaling is sent to port
5061 on the registrar server.
